The 25 kW three-phase inverter demonstrates unparalleled system level power density and efficiency by simply using a single Wolfspeed WolfPACK™ FM3 power module – a platform that has been optimized for Silicon Carbide MOSFETs in a compact, industry-standard footprint. This reference design is offered as a comprehensive design package to support early SiC design-in activities, enabling engineers to quickly evaluate performance out of the box as a simple three-phase inverter topology. The flexibility of the generic power stage also makes it simple to adapt to other applications, making it ideal for evaluating or scaling up to higher power levels in industrial motor drives, power supplies, and renewable energy applications, or as the bi-directional active front end (AFE) stage for off-board electric vehicle (EV) fast charging.
