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 12):
The method according to  claim 11 , further comprising changing between a first mode and a second mode;\n the first mode being a mode in which the converted voltage command value of the first phase is configured such that the output voltage of the first phase during the predetermined period is not less than the time average of the 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 in which the converted voltage command value of the second phase is configured such that the output voltage of the second phase during the predetermined period is less than the time average of the 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, and the second mode being a mode in which the converted voltage command value of the first phase and the converted voltage command value of the second phase are configured such that the output voltages of the first and second phases during the predetermined period are not less than the time averages of the target voltages of the first and second phases to be output in the cycle of the carrier respectively, and that the output voltages of the first and second phases during the remaining period are less than the time averages of the target voltages of the first and second phases respectively.
