ELECTRIC VEHICLE DRIVING DEVICE |
摘要 |
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 3 are provided in parallel for each inverter 6. Harmonic components generated by the brake-chopper switching circuits 3 are decreased by changing phases or frequencies of triangular carrier waves of the switching circuits 3, relatively to each other. |
