Totem-Pole Bidirectional Power Converter Reference Design for Electric Vehicles

Summary

This is a reference design for a Totem-Pole bidirectional power converter for electric vehicles.
By using SiC MOSFET, it can operate at high switching frequency, achieving high efficiency, small size and lightweight.

It can be used in high-power charging systems such as electric vehicle chargers, OBC, UPS and solar systems.
By using this reference design, users can accelerate the design of SiC MOSFET systems, thereby significantly shortening product development cycles.

This reference design interfaces seamlessly with ESC's "CLLLC Full-Bridge Bidirectional Power Converter for Electric Vehicles"
to build applications such as OBC.
The advantages

are about 40% smaller than IGBT, high output (6.6kW), high efficiency (more than 98%), digitally controlled bidirectional output, and adjustable output voltage.
