Abstract
A unitary on-board charger and generator (OBCG) for an electric vehicle system and method is disclosed. The OBCG includes a charging circuit with a diode bridge rectifier connected to an AC power source, a power factor correction converter, and a bi-directional DC/DC converter. The OBCG also includes a generating circuit with a a three-phase inverting circuit, three inductive coils connected to each leg of the three-phase inverting circuit, and a plurality of output capacitors connected to the outputs of the three inductive coils. The OBCG also includes a bridge capacitor and a control switching element connected between the charging circuit and the generating circuit for changing between a charging and generating state.
