3-phase 2-level full bridge PFC (Bidirectional)

Description

This type of three-phase bridge PFC is used when bi-directional power conversion to and from the three-phase AC grid is required. It is compatible with 170-480V, 3-phase power supply, and VBUS voltage up to 1000V is assumed.
Since it can be used for various power conversion applications, it can be used in EV-mounted On Board Charger and power storage systems.
