An apparatus and method employs a rectifier, switches, and power converter that comprises a first stage, a second stage and a direct current (DC) bus between the first and second stages, to: in a first state supply rectified DC current to the first stage and a voltage adjusted current from the second stage to a load, for example a power storage device (e.g., secondary battery, ultra-capacitor(s)) at a relatively high voltage (e.g., 48 V for traction motor), and in a second state supply DC current to the first stage from the power storage device and supply a voltage adjusted current from the second stage, for example to a lower voltage DC bus or load (e.g., 12 V). The rectifier can, for example, receive grid or mains AC power.
