Wolfspeed presents a new high-performance, low-cost, compact 3-phase inverter based on next generation power modules which are specifically optimized to fully utilize Wolfspeed’s third generation of Silicon Carbide (SiC) MOSFETs. The inverter was designed with a holistic approach with careful consideration of module specifications, busbar technology, DC link capacitors, and a high-performance thermal stackup. Parasitic elements of all critical components including the module, busbar, and capacitors are validated to ensure the lowest overall stray inductance. The XM3 module is 60% by volume smaller than equivalent power rated modules which enables the inverter to achieve a power density of 32 kW/L. The unit is tested under application conditions with an 800 V DC bus and 360 A phase current.
