The rapid growth of technology over the past century brought us as many advantages as many disadvantages including the accelerating global warming with its dramatic consequences we face every day in various parts of the Earth. So far no one found a solution how to stop this process, but there are many solutions how to slow it down.
Today we try to respond to this challenge with carbon neutrality initiatives launched in many countries across the globe. And one of the major steps in this green society program is the electrification of passenger and commercial vehicles.
Right now, companies have various approaches to vehicle electrification including mild-hybrid electric vehicles MHEV, full hybrid electric vehicles HEV, plug-in hybrid electric vehicles PHEV, battery electric vehicles BEV, and fuel-cell electric vehicle FCEV. What some time ago seemed like a big step forward is a reality we live in now.
And to make this dream come true became possible with the help of power semiconductors. For a long time, semiconductors were used in the automotive industry, and the evolution of power semiconductor materials pushed the transition to the electrification of vehicles. Electric vehicles’ performance and cost depend on the technical level of the motor control system.
Previously, silicon (Si) IGBT modules served as the heart of electronic control systems with their relatively high switching speed and low conduction loss. But with the growth of silicon carbide (SiC) technology, EVs step into the new era of electrification.
Silicon-based semiconductors have been dominating the market for many decades. No wonder, several generations of power electronics engineers were passing their knowledge and experience working with silicon semiconductors. Through time they have short-listed their preferred solutions produced by several companies.
Based on the current requirements for the improvement of battery life and dynamic performance of electric passenger and commercial vehicles, higher efficiency, and fewer parts and materials are required to further improve the power density of inverters and electric drive assemblies. All this becomes possible with the transition from Si to SiC power devices. But when it comes to the all-new silicon carbide semiconductors and the rapidly growing EV industry, many face difficulties to make the right choice of the silicon carbide devices available in the market.
Recently I launched a poll to understand what is most important for EV companies when choosing a supplier of SiC power devices. Power electronics engineers from the semiconductor and automotive industries shared their experience and unanimously confirmed that the performance of the power devices plays a crucial role when choosing a supplier. The poll results are:
- Performance/characteristics – 66%
- Price – 16%
- Lead time – 9%
- Brand – 9%
Based on the results it is clear that for the EV market today characteristics of SiC power devices and price play the most important role. After all, consumers want high performance and reliability at affordable prices.
Nowadays SiC is still more expensive than Si. However, the prices have dropped a lot in the past decade, and the growing number of SiC fabs promises to drop the price in the future. Fingers crossed, in the nearest future, the dream of the consumers for the high-performance, reliable, and affordable EV will come true.

Toshiba Electronic Devices & Storage Corporation has developed 2200 V silicon carbide (SiC) metal oxide semiconductor field effect transistors (MOSFETs) for photovoltaic (PV) inverters. A two-level inverter with the new devices realized higher frequency operation and lower power loss than a conventional three-level silicon (Si) insulated gate bipolar transistor (IGBT) inverter. The new MOSFETs also contribute to simplification of inverter systems and reductions in their size and weight.
Three-level inverters enjoy the advantage of low switching losses because the voltage applied to switching devices in the inverters during off-state is half the line voltage. Against this, two-level inverters have fewer switching modules than three-level inverters, realizing a simpler, smaller, and lighter system. However, they require semiconductors with higher breakdown voltage, as the applied voltage is equal to the line voltage. Also, demand for semiconductors with both low loss and high breakdown voltage is growing as 1500 V DC line voltage systems are introduced in photovoltaic and other renewable energy markets.
Toshiba Electronic Devices & Storage Corporation has developed 2200 V Schottky barrier diode (SBD)-embedded SiC MOSFETs for two-level inverters in 1500 V DC voltage systems. The impurity concentration and thickness of the drift layer has been optimized to maintain the same relationship between the on-resistance and the breakdown voltage as our existing products, and also to achieve high resistance to cosmic rays, a requirement for PV systems. It has also been confirmed that embedding SBDs clamped parasitic PN junctions between the p-base regions and the n-drift layer secure high reliability in reverse conduction.
Switching energy loss for the developed all-SiC module is far lower than for the Si module (Si IGBTs + Si fast recovery diodes) with the same 2000 V rated voltage class. Estimates of inverter power dissipation found that the developed SiC module achieves higher frequency operation twice that of a conventional Si IGBT, as well as a 37% lower loss for the two-level SiC inverter against the three-level Si inverter. The higher frequency operation enables downsizing and weight reduction of other system components, such as heat sinks and filters.

The University of Arkansas has taken the next step to becoming a national leader in the United States’ semiconductor economy. Semiconductors, such as silicon, are essential materials in most electronic devices and advance performance in fields such as healthcare, national defense, computing and transportation.
This August, the university began construction on the national Multi-User Silicon Carbide Research and Fabrication Facility, or MUSiC. Capable of silicon or silicon carbide chip fabrication, this new semiconductor research and fabrication facility will enable the government, businesses of all sizes, and universities to prototype in silicon carbide, introducing a capability that does not presently exist in the U.S.
This unique facility will offer low-volume prototyping for high-volume manufacturing, bridging the gap between traditional university research and the needs of private industry. This will accelerate both workforce development and technological advancement in semiconductors by providing a single location where chips can be go from developmental research to prototyping, testing and fabrication.
Alan Mantooth, Distinguished Professor of electrical engineering at the U of A, is principal investigator for MUSiC. He stated that with MUSiC, the university could “begin training the next generation at a variety of degree levels to provide well-trained and educated talent for onshoring semiconductor manufacturing that domestic suppliers offshored in the late 90s and early 2000s. Our training will be equally applicable to silicon and silicon carbide and other materials.”
Construction coincides with the CHIPS America Summit on Aug. 17, an invitation-only event for research, industry and governmental leaders from across the nation to discuss CHIPS and Science Act semiconductor-related opportunities and the ways in which the U of A and the State of Arkansas are uniquely positioned to lead.
The summit will feature Director of External and Government Affairs for the U.S Department of Commerce’s CHIPS Program Office, Adrienne Elrod. U.S. Representative Steve Womack and Arkansas Secretary of Commerce Hugh McDonald will also participate.
In addition to the MUSiC facility, the U of A is also home to the first Energy Frontier Research Center in Arkansas, as part of a team of researchers who received $10.35 million from the U.S. Department of Energy. The Center for Manipulation of Atomic Ordering for Manufacturing Semiconductors is dedicated to investigating the formation of atomic orders in semiconductor alloys and their effects on various physical properties. This research program will enable reliable, cost-effective and transformative manufacturing of semiconductors.
Researchers at the U of A previously established the MonArk NSF Quantum Foundry to accelerate the development of quantum materials and devices. In collaboration with Montana State University, and other member universities, the foundry supports the study of 2-D materials — consisting of a single layer of bonded atoms — by aiding researchers and facilitating the exchange of ideas across academia and industry. The project leads the fabrication of 2-D material quantum devices and their characterization, using low-temperature electronic transport and optoelectronic techniques.
The U of A’s existing and expanding research foundation means it’s uniquely positioned to take advantage of the recent CHIPS (Creating Helpful Incentives to Produce Semiconductors) and Science Act, which is providing approximately $280 billion in funding to stimulate domestic research and manufacturing of semiconductors.
As a result of manufacturing and production shortages of essential computer chips during the pandemic, which are overwhelmingly manufactured overseas, the federal government has prioritized the onshoring of this critical technology.
About the University of Arkansas: As Arkansas’ flagship institution, the U of A provides an internationally competitive education in more than 200 academic programs. Founded in 1871, the U of A contributes more than $2.2 billion to Arkansas’ economy through the teaching of new knowledge and skills, entrepreneurship and job development, discovery through research and creative activity while also providing training for professional disciplines.
The Carnegie Foundation classifies the U of A among the few U.S. colleges and universities with the highest level of research activity. U.S. News & World Report ranks the U of A among the top public universities in the nation. See how the U of A works to build a better world at Arkansas Research and Economic Development News.
The national Multi-User Silicon Carbide Research and Fabrication Facility, or MUSiC, will provide opportunities for the government and business of all sizes, and universities to prototype in silicon carbide, introducting a capability that does not currently exist in the U.S.

Transphorm, Inc. announced it has demonstrated up to 5 microsecond short circuit withstand time (SCWT) on a GaN power transistor with a patented technology. The achievement is the first of its kind on record, marking an important milestone for the industry as a whole. It proves Transphorm GaN’s ability to meet the required short circuit capabilities of rugged power inverters such as servo motors, industrial motors, and automotive powertrains served traditionally by silicon IGBTs or silicon carbide (SiC) MOSFETs— an over $3 billion GaN TAM over the next 5 years.
The demonstration was developed with support from Yaskawa Electric Corporation, a long-term strategic partner of Transphorm’s and a global leader in low and medium voltage drives, servo systems, machine controllers, and industrial robots. This makes GaN a highly attractive power conversion technology for servo systems, as it allows for higher efficiency and reduced size compared to incumbent solutions.
To do that, GaN must pass stringent robustness tests—of which, short-circuit survivability is the most challenging. In case of short-circuit faults, the device must survive extreme conditions with both high current and high voltage. The system can take up to a few microseconds to detect the fault and shut down the operations. During this time, the device must withstand the fault on its own.
“If a power semiconductor device cannot survive short-circuit events, the system itself may fail. There was a strong perception that GaN power transistors could not meet the short circuit requirements needed for heavy-duty power applications such as ours,” said Motoshige Maeda, Department Manager of Fundamental R&D Management Department, Corporate Technology Division, Yaskawa. “Having worked with Transphorm for many years, we believed that perception to be unfounded and have been proven right today. We’re excited about what their team has accomplished and look forward to demonstrating how this new GaN feature can benefit our designs.”
The short-circuit technology has been demonstrated on a newly designed 15 mΩ 650 V GaN device. Notably, that device reaches a peak efficiency of 99.2% and a maximum power of 12 kW in hard-switching conditions at 50 kHz. The device demonstrated not only performance, but also reliability, passing high-temperature high-voltage stress requirements.
“Standard GaN devices can withstand short-circuit for only a few hundredths of nanoseconds, which is too short for fault detection and safe shut-down. However, with our cascode architecture and key patented technology, we were able to demonstrate short-circuit withstand time up to 5 microseconds with no additional external components, thus retaining low cost and high performance,” said Umesh Mishra, CTO and Co-Founder, Transphorm.
“We understand the demands of high-power, high-performance inverter systems. We have a long history of strong innovation, and we’re proud to say that experience helped us bring GaN to the next level. This is yet another validation of Transphorm’s global leadership in high voltage GaN robustness and reliability and will be a gamechanger for GaN in motor drives and other high-power systems.”
The full description explaining the SCWT achievement, the demonstration analysis, and more is expected to be presented at a major power electronics conference next year.

Navitas Semiconductor announced that its CRPS185 3,200 W “Titanium Plus” server reference design not only surpasses the stringent 80Plus Titanium efficiency requirements, but also effectively satisfies the increasing power demands of AI data center power.
The rapid development and deployment of artificial intelligence (AI) including OpenAI’s ChatGPT, Microsoft’s Bing with AI, and Google’s Bard, has penetrated all aspects of people’s lives. New power-hungry AI processors like NVIDIA’s DGX GH200 ‘Grace Hopper’ demand up to 1,600 W each, are driving power-per-rack specifications from 30-40 kW up to 100 kW per cabinet. Meanwhile, with the global focus on energy conservation and emission reduction, as well as the latest European regulations, server power supplies must exceed the 80Plus ‘Titanium’ efficiency specification.
Navitas’ reference designs dramatically accelerate customer developments, minimize time-to-market, and set new industry benchmarks in energy efficiency, power density and system cost, enabled by GaNFast power ICs. These system platforms include complete design collateral with fully-tested hardware, embedded software, schematics, bill-of-materials, layout, simulation and hardware test results.
In this case, the ‘Common Redundant Power Supply’ (CRPS) form-factor specification was defined by the hyperscale Open Compute Project, including Facebook, Intel, Google, Microsoft, and Dell. Now, Navitas’ CRPS185 platform delivers a full 3,200 W of power in only 1U (40 mm) x 73.5mm x 185 mm (544 cc), achieving 5.9 W/cc, or almost 100 W/in3 power density. This is a 40% size reduction vs, the equivalent legacy silicon approach and easily exceeds the Titanium efficiency standard, reaching over 96.5% at 30% load, and over 96% stretching from 20% to 60% load, creating a ‘Titanium Plus’ benchmark, critical for data center operating models.
The CRPS185 uses the latest circuit designs including an interleaved CCM totem-pole PFC with full-bridge LLC. The critical components are Navitas’ new 650V GaNFast power ICs, with robust, high-speed integrated GaN drive to address the sensitivity and fragility issues associated with discrete GaN chips. Additionally, GaNFast power ICs offer extremely low switching losses, with a transient-voltage capability up to 800 V, and other high-speed advantages such as low gate charge (Qg), output capacitance (COSS) and no reverse-recovery loss (Qrr). As high-speed switching reduces the size, weight and cost of passive components in a power supply, Navitas estimates that GaNFast power ICs save 5% of the LLC-stage system material cost, plus $64 per power supply in electricity over 3 years.
Compared to traditional ‘Titanium’ solutions, the Navitas CRPS185 3,200 W ‘Titanium Plus’ design running at a typical 30% load can reduce electricity consumption by 757 kWh, and decrease carbon dioxide emissions by 755 kg over 3 years. This reduction is equivalent to saving 303 kg of coal. Not only does it help data center clients achieve cost savings and efficiency improvements, but it also contributes to the environmental goals of energy conservation and emission reduction.
In addition to data center servers, this solution can also be widely used in applications such as switch/router power supplies, communications, and other computing applications.
“The popularity of AI applications like ChatGPT is just the beginning. As data center rack power increases by 2x-3x, up to 100 kW, delivering more power in a smaller space is key,” said Charles Zha, VP and GM of Navitas China. “We invite power designers and system architects to partner with Navitas and discover how a complete roadmap of high efficiency, high power density designs can cost-effectively, and sustainably accelerate their AI server upgrades.”
