Abstract
A bidirectional power factor correction (PFC) module is coupled to an AC power source, an energy storage unit, and a DC bus. The bidirectional PFC module includes a bridge arm assembly and a control unit. The bridge arm assembly includes a first bridge arm, a first inductor, a second inductor, and a second bridge arm. The control unit provides a plurality of control signals to control the first bridge arm and the second bridge arm to make the bidirectional PFC module operate in an AC power supply mode, a DC power supply mode, or a power feed mode.
