In one embodiment, a bidirectional DC/DC converter includes a DC/AC inverter having active switches (e.g., MOSFETs), and an AC/DC rectifier having a capacitor that performs DC-bias current blocking and active switches (e.g., MOSFETs) arranged in a bridge configuration. A microcontroller is coupled to the active switches of the DC/AC inverter and AC/DC rectifier and configured to provide control signals thereto according to a control algorithm that, when power is to flow in a forward direction, sends control signals to operate the active switches of the DC/AC inverter at a duty cycle and to disable the active switches of the AC/DC rectifier, and when power is to flow in a reverse direction, sends control signals to operate the active switches of the DC/AC inverter to disable the active switches of the DC/AC inverter and operates the active switches of the AC/DC rectifier at a duty cycle.
