3-Phase AC 400V Input Vienna Rectifier PFC Power Supply

3-phase AC power is provided to industrial facilities, etc., and 400V (line voltage) systems are widely used outside Japan. When using such 3-phase AC 400V system inputs for EV chargers and other equipment, a PFC (Power Factor Correction) power supply that rectifies AC to DC with a high power-factor is essential.
This design is a PFC power supply that inputs a 3-phase AC 400V and outputs a DC 750V. A Vienna rectifier topology is used to achieve high-efficiency in 3-level operation, and power can be supplied to 5kW.
Design tips on each portion of the circuit, method of operation, and design information such as circuit diagrams and PCB patterns are available, please use them for your design.

This is a picture of the Vienna rectifier circuit PFC power supply that supports 3-phase AC 400V input.
