Cissoid releases SiC inverter control modules


Highly integrated modules can power SiC traction inverters with battery voltages up to 850V, at output power over 350kW

At the Applied Power Electronics Conference (APEC), Cissoid is releasing ts new series of SiC Inverter Control Modules (ICMs) for E-mobility applications.

The new CXT-ICM3SA series offers integrates Cissoid’s existing line of 3-phase 1200V/340A-550A SiC MOSFET Intelligent Power Modules (IPMs) with an OLEA T222 Field Programmable Control Unit (FPCU) control board and OLEA APP INVERTER application software, supplied in partnership with Silicon Mobility.

Depending on the selected ICM product, this modular core engine is capable of powering and controlling high voltage SiC traction inverters with battery voltages up to 850V, at output power in excess of 350kW, and with peak efficiency above 99 percent..

According to Cissoid, this integration facilitates the rapid development of SiC inverters by solving head-scratching EMC issues often generated due to fast-switching SiC transistors, by supporting different modulation schemes, e.g. SVPWM or DPWM, combined with dead time compensation, and by offering advanced motor control algorithms, including Field Oriented Control (FOC) and Flux Weakening management.

Cissoid also has a complete SiC inverter reference design allowing motor bench testing of the ICM together with key peripheral elements such as current sensors, a high-performance DC-Link capacitor and EMI filter.
