Cissoid and Silicon Mobility partner for SiC inverters 

High temperature semiconductor and power module provider, Cissoid has partnered with field programmable controller unit (FPCU) semiconductor supplier, Silicon Mobility to integrate the latter’s OLEA FPCU controller with the former’s SiC intelligent power module (IPM) offering. 

The resulting modular SiC inverter is expected to accelerate the development of compact and efficient SiC inverters for electric vehicle (EV) motor drives.

The SiC inverter offering consists of a power module and gate driver with protection and fault management, together with a fast FPCU controller and its application software optimised for e-motor control. Cissoid’s IPMs integrate a three-phase 1200V / 340 to 550A SiC MOSFET power module with a temperature-robust gate driver enabling low switching losses and high power density. Silicon Mobility OLEA FPCU controller and OLEA App Inverter software enable fast and efficient electric motor control, says Cissoid.

Pierre Delatte, CTO of Cissoid, commented: “The capability of SiC power modules to switch faster and to operate at higher frequencies makes it essential to have access to a controller technology capable of running real-time algorithms faster. OLEA FPCU low power consumption is also a key advantage in building highly compact and efficient traction inverters”.  

“By combining Cissoid technology with our OLEA control solution, we are offering a . . . hardware and software platform that will make possible the development of efficient and critically safe SiC inverters in only a few months,” added David Fresneau, vice president Marketing and Business Development at Silicon Mobility .

The SiC inverter platform is planned to be made available for customers by early Q2-2022. 

Cissoid specialises in high temperature semiconductors and power modules.

With a focus on the automotive market, Cissoid delivers high voltage gate drivers for SiC  and GaN transistors, power modules featuring low inductances and enhanced thermal performance, and automotive grade components rated at 175 degrees C in excess of the AEC-Q100 Grade 0 qualification standard.

For the aviation, industrial and oil and gas markets it provides products for harsh environment signal conditioning, motor control, timing and power supplies that provide reliable operation from -55 to +225 degrees C. 

Silicon Mobility invented FPCU semiconductor architecture for fast and critically safe real-time control. Silicon Mobility designs, develops, and sells flexible, real-time, safe, and open semiconductors for the automotive industry used to increase energy efficiency and reduce pollutant emissions while keeping passengers safe. 

Silicon Mobility’s products control electric motors, battery, and energy management systems of hybrid and electric vehicles. By using Silicon Mobility’s technologies, manufacturers improve the efficiency, reduce the size, weight, and cost of electric motors, and increase the battery range and durability. Its technologies and products accelerate the car’s powertrain electrification for OEMs. 

Silicon Mobility is headquartered in Sophia- Antipolis, France, with a presence in Germany, the USA, China, and Japan.
