Title: MOTOR-DRIVING DEVICE AND AIR CONDITIONER
Abstract:
The present invention provides a motor-driving device for driving a motor, the device being provided with the same number of inverter modules as the number of phases of the motor. Each of the inverter modules is provided with a plurality of switching-element pairs each composed of two switching elements connected in series. In each of the inverter modules, the plurality of switching-element pairs are connected in parallel. The resistance values of gate resistors Rg1 connected to the switching elements are set individually for each of the connected switching elements.
