摘要： The present invention is provided with: the same number of inverter modules 6-8 as the number of phases of an electric motor; and an inverter control unit 4 which generates pulse width modulation (PWM) signals for driving the inverter modules by way of PWM. Three phase outputs of each of the inverter modules are combined to obtain a phase output signal for one phase of the electric motor. Furthermore, capacitors 22, 32, 42 are mounted between control GNDs of the inverter modules 6-8 and power GNDs of the inverter modules. Accordingly, the application of surge voltage to switching elements 9e-9f can be inhibited, even if surge voltage is generated in GND wiring during switching operations of switching elements 9a-9f of the inverter modules.
