摘要： There is provided a modulating wave signal creation method for a PWM inverter controlled by a pulse width modulation signal obtained by comparing a modulating wave signal of a voltage instruction with a carrier. That is, there are provided a motor control device and a modulating wave signal creation method for a PWM inverter of the motor control device. The motor control device includes a modulating wave upper limit value calculation unit (105) and a modulating wave control unit (4). The modulating wave upper limit value calculation unit (105) creates a modulating wave upper limit value (14) for setting an upper limit value in the range not greater than the carrier maximum value and greater than the carrier minimum value, on a modulating wave. By using this modulating wave upper limit value (14), the modulating wave control unit (4) corrects the modulating wave instruction (13) of a plurality of phases.
