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 30):
The inverter according to  claim 29 , wherein the inverter is a three-phase inverter including the three series circuits, and\n the inverter is configured, 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 to generate 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, \n to use a converted voltage command value for a second phase 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 to use a converted voltage command value for a third phase 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.
