Abstract:
In a control apparatus, a controller perfoi ins comparison between a command voltage and a cyclic carrier signal to thereby perform one of pulse-width modulation upon each of first positive and negative peaks of the command voltage being within or identical to the corresponding one of second positive and negative peaks of the cyclic carrier signal, and single-pulse modulation upon each of the first positive and negative peaks of the command voltage being outside the corresponding one of the second positive and negative peaks of the cyclic carrier signal. The pulse-width modulation generates, for each cycle of the command voltage, plural drive pulses based on a result of the comparison. The single-pulse modulation generates, for each cycle of the command voltage, a single positive pulse and a single negative pulse for each cycle of the command voltage based on a result of the comparison.

Claim (Index 8):
The control apparatus according to  claim 4 , wherein:\n the cyclic carrier signal is a triangular carrier signal; the number of the carrier pulses of the triangular carrier signal for each cycle of the command voltage is referred to as K; the number K of the carrier pulses of the triangular carrier signal for each cycle of the command voltage satisfies the following equation:\n K= 3*(2 d +1) \n where d is an integer equal to or more than zero; and the controller is configured to:\n change, in the single-pulse modulation, the number K of the carrier pulses of the triangular carrier signal for each cycle of the command voltage to a different number of a switched triangular carrier signal; \n determine whether an absolute value of a difference between the number K of the triangular carrier signal and the different number of the switched triangular carrier signal is a natural-number multiple of 6 and a natural-number multiple of 12; and \n perform one of a first task and a second task upon determining that the absolute value of the difference between the number K of the triangular carrier signal and the different number of the switched triangular carrier signal is a natural-number multiple of 6 and not a natural-number multiple of 12, \n the first task reversing a polarity of the switched triangular carrier signal, the second task shifting the switched triangular carrier signal by a half cycle of the switched triangular carrier signal.
