Abstract: A battery charger capable of receiving AC power and delivering both AC and DC power to an electric power storage battery in accordance to different embodiments disclosed herein using a rectifier circuit supplying the DC load and absorbing power as a five-level active rectifier with low harmonics on the AC input. In one aspect, the battery charger may have a bidirectional rectifier/inverter converter providing power conversion between a DC source and AC enabling the user to not only charge an electrical vehicle (“EV”) but also convert the energy charged in the EV/battery or solar panel to AC for use.
