Switchable bidirectional power converter with single power factor correction circuit and on board charger therewith

Abstract

A switchable bidirectional power converter can comprise an interleaved bridge configuration. A multi-phase grid connection to a half-bridge multi-phase switching bank can comprise a first switching half-bridge leg. A single-phase grid connection to a full-bridge single-phase switching bank can comprise the half-bridge multi-phase switching bank interleaved with the full-bridge single-phase switching bank. The full-bridge single-phase switching bank can comprise the first switching half-bridge leg and a second switching half-bridge leg. A capacitor switch can be configured to switch at least two power factor correction capacitors between a parallel connection and a serial connection. The serial connection also includes a center tapping connection to the second switching half-bridge leg. Such a power converter can be used in a bidirectional on-board charger. Ultra-wide range voltages can be handled bidirectionally.
