33 kW High-Efficiency Bi-Directional Active Neutral Point Clamped (ANPC) Converter with Wolfspeed Gen 4 Technology
CRD-33FF12N-K
1500 V DC bus solar applications are rapidly growing due to the higher efficiency and higher power levels required in modern installations. This reference design demonstrates the use of Wolfspeed’s 1200 V Gen 4 silicon carbide (SiC) MOSFETs to optimize the performance of an Active-Front End of Power Conversion Systems (PCS), Solar Inverters and other similar applications. A single phase of a 100 kW AC-DC/DC-AC converter is demonstrated in the this design as a 33 kW Single phase leg. Utilizing Wolfspeed’s Gen 4 technology for these applications can improves system efficiency, increases power density and lowers the weight of the inverter compared to silicon solutions. Paralleling multiple discrete SiC devices is also demonstrated in this design which can be scaled up to 67 kW for a 200 kW Inverter.
