Abstract:
A control method of an inverter for outputting polyphase alternate-current electrical power is provided. In the control method, modified PWM pulses of respective phases for controlling semiconductor switching elements of the inverter are generated, based on an output of a counter common to the respective phases. Each of the modified PWM pulses is configured such that a total pulse width, in a period corresponding to one or more cycles of a carrier, is substantially equal to a total pulse width of an assumed PWM pulse which is obtained by comparing, with the carrier, a time average value of an output voltage of the corresponding phase in the period. Further, at least one of a generation timing and a generation frequency of at least one of the modified PWM pulses is changed from the assumed PWM pulse.

Claim (Index 4):
The method according to  claim 1 , wherein the inverter is a three-phase inverter including the three series circuits, and\n in the generating of the modified PWM pulses, in a case in which the modified PWM pulses of the period corresponding to one or more cycles of the carrier is to be generated,\n a modified PWM pulse for a first phase for controlling the semiconductor switching elements so as to hold an AC output voltage of the first phase at a voltage of a positive electrode or a negative electrode of the DC voltage source is generated, \n a converted voltage command value for a second phase is used for generating a modified PWM pulse for the second phase in which at least one of the generation timing and the generation frequency is changed from the assumed PWM pulse, and \n a converted voltage command value for a third phase is used for generating a modified PWM pulse for the third phase in which at least one of the generation timing and the generation frequency is changed from the assumed PWM pulse.
