Abstract

An power system for an electric motor vehicle includes a power electronics unit connected to battery-side terminals, motor-side terminals and power source-side terminals. The power electronics unit including a plurality of half-bridges, each of the half-bridges including a pair of switches, each of the half-bridges connecting to a respective one of the motor-side terminals, the power electronics unit being operable to direct current from a power source through an electric motor to a battery to charge the battery by repeatedly operating the electric motor in an inductor field building phase, and then an inductor field collapse phase. The power electronics unit is operable to supply current from the power source to electric motor to establish inductor fields in the electric motor in the inductor field building phase. The power electronics unit is operable to supply current from the electric motor to the battery upon a collapse of the established inductor fields in the electric motor in the inductor field collapse phase. At least one of the half-bridges of the power electronics unit includes or is directly connected to the first power source-side terminal.
