Product overview
Description
The STDES-SICGP4 reference design allows evaluating the switching and thermal performance of power SiC MOSFETs in an HiP247-4 (four-lead) package in a half-bridge topology.
The MOSFETs are controlled by isolated gate drivers. Drivers are supplied by isolated DC-DC converters.
The system requires the connection of an external inductor, a source, a load, an auxiliary supply, and PWM signals. It can be used to test operation in buck or boost configuration.
It is possible to use a low inductance shunt or to assemble a coaxial shunt to measure current through the low side MOSFET. In this perspective, the board can be used as a tool for double pulse test (DPT), to measure overshoot (voltage and current), speed (di/dt; dv/dt), and switching energy (EON; EOFF; ERR).
