Abstract
According to one embodiment, there is provided an electric-vehicle driving apparatus which consumes regenerative energy by a brake resistor and can decrease harmonic components generated by a brake-chopper switching circuit. Plural brake-chopper switching circuits are provided in parallel for each inverter. Harmonic components generated by the brake-chopper switching circuits are decreased by changing phases or frequencies of triangular carrier waves of the switching circuits, relatively to each other.
