Abstract:
A control circuit for a power converter includes a voltage command unit that generates a voltage command signal, a voltage command compensation unit that compensates the voltage command signal to generate a compensatory voltage command signal, and a switching pattern arithmetic unit that generates a switching signal for each of semiconductor switching elements of the power converter based on the compensatory voltage command signal and a carrier wave. The conversional fundamental frequency of the power converter is f and the carrier frequency of the carrier wave is fc. The voltage command compensation unit generates a compensation signal including at least one compensatory frequency component of fc−n×f (where n denotes successive positive and negative integers), and generates the compensatory voltage command signal.
