Two European companies have teamed up to develop a high performance field programmable silicon carbide power module for electric vehicle (EV) motor drives.

Belgian power module maker Cissoid is working with French chip designer Silicon Mobility to use the OLEA field programmable controller in an Intelligent Power Module (IPM) platform. The combination will accelerate the development of compact and efficient SiC Inverters for EV motor drives from 800V battery packs.

The partnership will deliver a SiC Inverter modular platform offering highly integrated hardware and optimized software: a power module and its gate driver with protection and fault management, an ultra-fast FPCU controller and its application software optimized 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. Silicon Mobility’s OLEA FPCU controller and OLEA App Inverter software 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,” said David Fresneau, VP Marketing and Business Development at Silicon Mobility. “By combining Cissoid technology with our OLEA control solution, we are offering 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.
