The new CXT-ICM3SA series offers hardware and software integration of the company’s existing line of 3-phase 1,200-V/340 to 550-A 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. Both the FPCU and the control software are ISO-26262 ASIL C/D certified and AUTOSAR 4.3 compliant.
The integration helps accelerate the development of SiC inverters by solving EMC issues often due to fast-switching SiC transistors. This is achieved by supporting different modulation schemes, such as SVPWM or DPWM, combined with dead time compensation, and by offering advanced motor control algorithms, including field-oriented control (FOC) and Flux Weakening management, the company said.
Depending on the ICM product, this modular core engine is capable of powering and controlling high-voltage SiC traction inverters with battery voltages up to 850 V, at output power in excess of 350 kW and with peak efficiency above 99%, Cissoid said. The ICM also enables high switching frequencies up to 50 kHz thanks to the combination of the low-loss SiC power module and ultra-fast real-time FPCU.
Cissoid offers a complete SiC inverter reference design that allows motor bench testing of the ICM together with key peripheral elements such as current sensors, a high-performance DC-Link capacitor and EMI filter. Both the ICM and the reference design are available from the company, along with the motor control software and on-site technical support. Cissoid is exhibiting at APEC 2024, booth #452.
