STMicroelectronics EVSTGAP2SICSAC Demonstration Board

STMicroelectronics EVSTGAP2SICSAC Demonstration Board is designed to evaluate the STGAP2SICSAC isolated single gate driver and drives a half-bridge power stage with up to a 520V voltage. This demonstration board allows the user to increase bus voltage by replacing the power switches with appropriate devices in H2PACK-7L or H2PACK-2L, or HU3PAK package. The EVSTGAP2SICSAC board implements negative gate driving, and the onboard isolated DC-DC converters allow working with optimized driving voltage for SiC MOSFET. This demonstration board is ideal for mid and high-power inverter applications such as motor drivers in industrial applications equipped with SiC MOSFET power switches.

Features
