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 9):
The method according to  claim 8 , wherein\n the converted voltage command value of a first phase of at least two phases among the respective three phases is configured such that an output voltage of the first phase during the predetermined period is not less than a time average of a target voltage of the first phase to be output in the cycle of the carrier, and that the output voltage of the first phase during the remaining period is less than the time average of the target voltage of the first phase, and the converted voltage command value of a second phase of the at least two phases is configured such that an output voltage of the second phase during the predetermined period is less than a time average of a target voltage of the second phase to be output in the cycle of the carrier, and that the output voltage of the second phase during the remaining period is not less than the time average of the target voltage of the second phase.
