The global market for photovoltaic energy storage systems (PV-ES) has grown at a high speed in the last years. As competition in the PV-ES market accelerates, improving power density has become key to success, and how to improve efficiency and power density for energy storage applications has attracted much attention. Infineon’s CoolSiC MOSFET 1200 V and IGBT7 H7 1200 V series power semiconductor devices adopt the latest semiconductor technologies and design concepts that are tailored to industrial applications.
Mr. Yu Daihui, Senior Vice President and Head of Industrial & Infrastructure of Infineon Technologies Greater China said, “As an industry leader in power semiconductors, we are proud to work closely with FOXESS. We will continue to drive decarbonization by enabling higher power density and more reliable systems for PV-ES applications.”
Mr. Zhu Jingcheng, Chairman of FOXESS, said, “Thanks to the support of Infineon’s advanced components, FOXESS’ products have been significantly improved in terms of reliability and efficiency. This has been an important driving force for FOXESS’ growth. Infineon’s technical support and product quality have not only strengthened our competitiveness, but also expanded our presence in the market. We are confident about the future and look forward to further cooperation with Infineon to jointly promote the development of the industry and create greater value for our customers.”
With a high power density, Infineon’s CoolSiC MOSFETs 1200 V can reduce losses by 50 percent and provide ~2 percent additional energy without increasing the battery size, which is especially beneficial for high-performance, lightweight, and compact energy storage solutions. FOXESS’ H3PRO 15 kW-30 kW energy storage series uses Infineon’s CoolSiC MOSFETs 1200 V for all models. Thanks to Infineon’s excellent performance, the H3PRO series has achieved an efficiency of up to 98.1 percent and excellent EMC performance; with superior performance and reliability, the H3PRO series has seen rapid sales growth in the global market.
Infineon’s TRENCHSTOP IGBT7 H7 650 V / 1200 V series has lower losses and helps improve the overall efficiency and power density of inverters. In high-power inverter projects, high-current mold packaged discrete devices with current handling capability above 100 A can reduce the number of IGBTs in parallel and replace the IGBT module solution, further improving system reliability and reducing costs; in addition, the H7 series has become an industry benchmark for its high-quality performance and greater resistance to humidity.
At present, FOXESS’ main industrial and commercial model, the R Series 75-110 kW, redefines the overall design of the 100 kW model by using IGBT7 H7 series discretes, and the efficiency of the whole machine can reach up to 98.6 percent. Thanks to the low power loss and high power density of the IGBT7 H7 series in discrete packages, technical problems such as current sharing in the paralleling process can be simplified and optimized.
Every power device needs a driver, and the right driver can make the design a lot easier. Infineon offers more than 500 EiceDRIVER gate drivers with typical output currents of 0.1 A~18 A and comprehensive protection functions including fast short-circuit protection (DESAT), active Miller clamp, shoot-through protection, fault reporting, shutdown, and overcurrent protection, suitable for all power devices including CoolSiC and IGBTs.

The aviation industry’s requirements for the latest, most efficient and lowest-emission aircraft is propelled by an overarching goal towards sustainability and decarbonization. To satisfy these goals, aviation power systems developers are transitioning to electric actuation systems as the trend towards More Electric Aircraft (MEA) continues to grow.
To provide the aviation industry with a comprehensive electric actuation solution, Microchip Technology announced a new integrated actuation power solution that combines companion gate driver boards with the expansive Hybrid Power Drive (HPD) modules in silicon carbide or silicon technology with a power range of 5 kVA to 20 kVA.
The new integrated actuation power solution maintains the same footprint regardless of the power output. The companion gate driver boards are designed to be integrated with Microchip’s HPD modules to provide an all-in-one motor drive solution for the electrification of systems such as flight controls, braking and landing gear. Microchip’s power solutions are designed to scale based on the requirements of the end application, from smaller actuation systems for drones to high-power actuation systems for Electric Vertical Take-Off and Landing (eVTOL) aircraft, MEA and all-electric aircraft.
“We developed the companion gate driver boards to be used with our existing HPD modules to bring to market a plug-and-play power solution for MEA,” said Leon Gross, vice president of Microchip’s discrete product group. “With this solution, customers no longer need to design and develop their own drive circuitry, which can reduce design time, resources and cost.”
These high-reliability devices are tested to conditions outlined in DO-160, “Environmental Conditions and Test Procedures for Airborne Equipment.” There are multiple protection features including shoot-through detection, short circuit protection, desaturation protection, Under Voltage Lock Out (UVLO) and active miller clamping.
The gate driver boards are designed to be driven with external PWM signals based on Low Voltage Differential Signaling (LVDS) compliant with TIA/EIA-644 for low Electromagnetic Interference (EMI) and good noise immunity. The gate driver board provides differential outputs for telemetry signals like DC bus current, phase current and solenoid current by taking feedback from shunts present in the HPD module and DC bus voltage. It also provides direct output of two PT1000 temperature sensors available in the HPD power module.
The companion gate driver boards are low-weight, low-profile and compact solutions to optimize size and power efficiency of actuation systems. The gate drivers are designed to operate throughout the temperature range of −55°C to +110°C, which is critical for aviation applications that are often exposed to harsh environments.
The isolated companion gate driver boards only require a single 15V DC input for the control and drive circuit; additional voltages needed can be generated on the card. This significantly reduces the number of system components and simplifies system cabling.
Microchip provides comprehensive solutions for MEA by integrating power products with FPGAs, microcontrollers, security, memory and timing. Microchip’s solutions are designed to help customers speed up their development, reduce costs and get to market faster.

The customer is multiple billion dollar per year global semiconductor company with locations across Europe, Asia, and the Americas that serves various industries including automotive, industrial, mobile, and consumer applications. The FOX-NP system, including the FOX WaferPak Aligner and initial WaferPaks, are scheduled to ship over the next few months.
The FOX-NP system is configured with the new Bipolar Voltage Channel Module (BVCM) and Very High Voltage Channel Module (VHVCM) options that enable new advanced test and burn-in capabilities for silicon carbide power semiconductors using Aehr’s proprietary WaferPak full wafer Contactors.
Gayn Erickson, President and CEO of Aehr Test Systems, commented, “We are very excited that this new customer selected our FOX-P solution for engineering, qualification, and production of their silicon carbide power devices. After working with the Aehr team and our technology solutions over an extended period of time, they felt secure in our ability to aid them in achieving these goals. A key feature in their selection of our FOX solution is its proven ability to cost-effectively implement their target burn-in and stabilization requirements, including 100% traceability and proof that every device on the wafer is burned in for the needed test duration.
“This customer currently has a wide range of automotive products and is entering the silicon carbide market to address several applications that include automotive, industrial, and electrification infrastructure. Key capabilities of our solution include our ability to scale from engineering and qualification and small lot production with the FOX-NP system to large scale production with the FOX-XP with Automated WaferPak Aligner. They have told us that they plan to transition to our FOX-XP multi-wafer test and burn-in systems for high-volume production. Aehr’s FOX-P technology facilitates a seamless transition from engineering to high-volume production with 100% compatibility between systems.
“This customer sees the enormous opportunity for silicon carbide power devices in industrial and power applications.

The cost of ownership of our solution proves to be more cost-effective and efficient for these devices than package part burn-in after the die are packaged. This is a strong testimony of the advantage of wafer level burn-in as a better alternative to package part burn-in.
“The FOX family of compatible systems including the FOX-NP and FOX-XP multi-wafer test and burn-in systems and Aehr’s proprietary WaferPak full wafer contactors provide a uniquely cost-effective solution for burning in multiple wafers of devices at a single time to remove early life failures of silicon carbide devices, which is critical to meeting the initial quality and long-term reliability of the automotive, industrial, and electrification infrastructure industry needs.”
The FOX-XP and FOX-NP systems, available with multiple WaferPak Contactors (full wafer test) or multiple DiePakTM Carriers (singulated die/module test) configurations, are capable of functional test and burn-in/cycling of devices such as silicon carbide and gallium nitride power semiconductors, silicon photonics as well as other optical devices, 2D and 3D sensors, flash memories, magnetic sensors, microcontrollers, and other leading-edge ICs in either wafer form factor, before they are assembled into single or multi-die stacked packages, or in singulated die or module form factor.

In the paper “Milliseconds Power Cycling (PCmsec) Driving Bipolar Degradation in Silicon Carbide Power Devices”, Sibasish Laha from Fraunhofer IISB and his co-authors Jürgen Leib, Andreas Schletz, Martin Maerz, Christian Liguda, Firas Faisal and Davood Momeni describe an innovative approach to silicon carbide (SiC) power cycling.
Until now, bipolar degradation (BD) tests have not been sufficiently differentiated in the investigation of failure and fault mechanisms for SiC power devices. SiC power products may experience voltage degradation which stems from the stacking faults (SFs) growth, commonly known as BD. To properly evaluate the BD impact on the electric performance of devices, it is important to distinguish it from other stress-related degradation such as power metal or interconnection.
This aspect has not yet been addressed, although the BD mechanism is well understood. The paper outlines a methodology by modifying the power cycling test (PCsec) to PCmsec in order to systematically investigate the effect of BD while controlling the impact of thermal degradation. This method enables a thorough evaluation of the distinct influences of both degradation contributors.
The complete paper will soon be available in the CIPS proceedings. Until then, feel free to download the paper presentation on event page.
