CISSOID and Silicon Mobility to develop compact and efficient SiC inverters

1 min read

CISSOID and Silicon Mobility, the developer of the FPCU (Field Programmable Controller Unit) semiconductor architecture have announced the integration of Silicon Mobility's OLEA FPCU controller with CISSOID's Silicon Carbide (SiC) Intelligent Power Module (IPM) platform.

This integrated platform will help to accelerate the development of compact and efficient SiC Inverters for EV motor drives.

The partnership is looking to deliver a SiC Inverter modular platform that offers highly integrated hardware and optimised software: a power module and its gate driver with protections and fault management, an ultra-fast FPCU controller and its application software optimised for e-motor control.

CISSOID's IPMs integrate a 3-Phase 1200V/340A-550A SiC MOSFET Power Module with a temperature-robust gate driver enabling low switching losses and high power density, while Silicon Mobility's OLEA FPCU controller and OLEA APP INVERTER software will enable fast and highly efficient electric motor control.

"Silicon Mobility ultra-fast OLEA FPCU is the perfect technology to control our SiC IPM platform in motor drive applications," said Pierre Delatte, CTO of CISSOID. "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".

"CISSOID SiC IPM platform is a great technology in helping to accelerate the development of SiC power converters", added David Fresneau, VP Marketing and Business Development at Silicon Mobility. "By combining CISSOID technology with our OLEA control solution, we are able to offer a unique hardware and software platform that will make possible the development of efficient and critically safe SiC inverters in only a few months".

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