Cissoid and Silicon Mobility deliver SiC inverter design


Reference design supports electric motor drives up to 350kW/850V

Cissoid and Silicon Mobility have announced a partnership to deliver a complete and modular 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 EV 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 two 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 customise for the application requirements.”

Following this agreement, customers can now buy a complete SiC inverter reference design from Cissoid together with a licence 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 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.”
