DENSO CORPORATION announced that it has developed its first-ever inverter with silicon carbide (SiC) semiconductors. This inverter, which is incorporated in the eAxle, an electric driving module developed by BluE Nexus Corporation, will be used in the new RZ, Lexus’ first dedicated battery electric vehicle (BEV) model has been released on March 30, 2023.
SiC power semiconductors consist of silicon and carbon that significantly reduce power loss compared with silicon (Si) power semiconductors. The verification of cruising test in a certain condition, which test was performed by BEV consisted of SiC semiconductor inverters, demonstrated inverters with SiC power semiconductor reduce power loss less than half of ones with Si semiconductor. As a result, the energy efficiency of BEVs is improved and cruising range is extended.
Key elements of developing the new inverter:
- SiC power semiconductors with DENSO’s unique trench-type metal-oxide-semiconductor (MOS) structure improve the output per chip due to reducing the power loss caused by heat generated. The unique structure achieved high voltage and low on-resistance operation.
Key elements of manufacturing the new inverter:
- Based on the high-quality technology jointly developed by DENSO and Toyota Central R&D Labs., Inc., we utilize SiC epitaxial wafers that incorporate the results of work commissioned by New Energy and Industrial Technology Development Organization (NEDO). As a result, we have halved the number of crystal defects that prevent the device from operating normally due to the disorder of the atomic arrangement of the crystal.
- By reducing crystal defects, the quality of SiC power semiconductor devices used in vehicles and their stable production are ensured.
DENSO calls its SiC technology “REVOSIC®,” and uses it to comprehensively develop technologies for products ranging from wafers to semiconductor devices and modules such as power cards.
DENSO will contribute to the realization of a carbon-neutral society through development aimed at more efficient energy management for vehicles, while also utilizing the grant from Green Innovation Fund (GI Fund), which was adopted in 2022.

While the adoption of GaN devices has expanded in recent years due to their superior high-speed switching characteristics, the speed of Control ICs, which are responsible for directing the driving of these devices, has become challenging.
In response, ROHM has further evolved its ultra-high-speed pulse control technology Nano Pulse Control™. It is cultivated for power supply ICs, succeeding in significantly improving the control pulse width from the conventional 9ns to an industry-best 2ns. Leveraging this technology allowed ROHM to establish its ultra-high-speed Control IC technology that maximizes the performance of GaN devices.
When pursuing miniaturization of the power supply circuit, it is necessary to reduce the size of the peripheral components through high-speed switching. Achieving this requires a Control IC that can take advantage of the drive performance of high-speed switching devices such as GaN devices.
To propose solutions that include peripheral components, ROHM established ultra-high-speed Control IC technology optimized for GaN devices utilizing proprietary analog power supply technology Nano Pulse Control™.
ROHM is currently working to commercialize Control ICs utilizing this technology, with plans to start sample shipment of 100V 1ch DC-DC Control IC in the second half of 2023. Using in conjunction with ROHM GaN devices (EcoGaN™ series) is expected to result in significant energy savings and miniaturization in a variety of applications, including base stations, data centers, FA (Factory Automation) equipment, and drones.
Going forward, ROHM will continue to develop products that solve social issues by pursuing greater ease-of-use in applications centered on its strengths in analog technology.

CISSOID and Silicon Mobility have announced a far-reaching partnership to deliver a complete and modular Silicon Carbide (SiC) inverter reference design supporting electric motor drives up to 350kW/850V. The reference design includes CISSOID’s high voltage SiC-based power module, integrated Gate Driver board, Control board with Silicon Mobility’s ultra-fast and safe OLEA T222 FPCU, DC and phase current sensors, DC link capacitor and EMI filtering together with integrated liquid cooling. CISSOID will also sell and deliver Silicon Mobility’s OLEA® APP INVERTER Software for Electric Vehicle Powertrain Control providing the customer with a development platform ready for integration work.
Dave Hutton, CISSOID’s CEO commented: “Up until now, customers only really had 2 options. The first was to develop all the hardware, then integrate with third party software into their design environment. This was extremely time consuming and required in depth knowledge of SiC-based power system design. The second option was to buy an off-the-shelf inverter that, however, does not offer the ability to fully customize for the application requirements.”
Following this agreement, customers can now buy a complete SiC inverter reference design from CISSOID together with a license to use the Silicon Mobility’s OLEA® APP INVERTER control software and design on top its software application. CISSOID will also provide the technical support to integrate the inverter into the end-application.
Once the design is completed, the customer can choose to purchase the entire inverter Bill-of-Material (BOM) from CISSOID or just the SiC Intelligent Power Module (IPM) and Control Board, while purchasing other components and Inverter housing from their preferred suppliers. The customer can then integrate the inverter into their motor drive system prior moving to production.
David Fresneau, VP Marketing and Business Development at Silicon Mobility added: “This is a great opportunity for our customers to get access to our advanced e-motor control hardware and software platform and a fully integrated high performance inverter reference design from CISSOID which will significantly simplify the design process and reduce Time-to Market.
