Reference Design – Documentation Only – No Hardware
This reference design demonstrates the application of Wolfspeeds WolfPACKTM power modules to create a bidirectional high power density Active Front End (AFE) that can be applied to electric vehicle (EV) fast charging, industrial motor drives, power supplies and renewable energy applications. The design is ideal for scaling up to higher power levels by interleaving multiple 25kW AFE AFE’s. The use of a single power module with an isolated substrate simplifies the system design with commonly used thermal management techniques. The use of Wolfspeed’s third generation C3M MOSFET MOSFET’s enables high switching frequencies and faster switching speeds resulting in increased control bandwidth and power factor as well as smaller magnetics and DC Bus Capacitors.
