Switchable bidirectional power converter with single power factor correction circuit and on-board charger having same

The invention discloses a switchable bidirectional power converter. The switchable bidirectional power converter may include an interleaved bridge configuration. A multi-phase grid connection to the half-bridge multi-phase switching block may include a first switching half-bridge arm. A single-phase grid connection to a full-bridge single-phase switching block may include the half-bridge multi-phase switching block interleaved with the full-bridge single-phase switching block. The full-bridge single-phase switch group can comprise the first switch half-bridge arm and the second switch half-bridge arm. The capacitor switch may be configured to switch the at least two power factor correction capacitors between a parallel connection and a series connection. The parallel connection may be connected to the single-phase switching block, the first switching half-bridge arm, and the second switching half-bridge arm. The series connection may be connected to the multi-phase switching group and the ...
