Wolfspeed has announced a gate driver board that supports the company's 1.2kV SiC MOSFET power modules in two-level, three-phase inverter applications. The CGD15FB45P1 features a direct-mount low-inductance design and furnishes six output channels and an isolated power supply, as well as short-circuit, overtemperature and undervoltage protection.

The CGD15FB45P1 offers a smaller footprint and enhanced functionality compared to its predecessor. For example, the driver's increased power per channel enables a higher maximum switching frequency of 250kHz. It also occupies a footprint of just 152.4mm x 168.6mm.


The gate driver is intended for the CCS020M12CM2 and CCS050M12CM2 SiC MOSFET 45mm six-pack modules. These SiC MOSFET modules reduce switching loss and can replace Si IGBT modules of much higher rated current, the company indicated.

The CGD15FB45P1 gate driver board is available from Wolfspeed distributor RichardsonRFPD.
