ABSTRACT:
A control apparatus for an inverter including a filter consisting of a reactor and a capacitor, connected to the output terminal thereof is operative to compute such a voltage correction value to cancel a voltage difference between the reference voltage and the output voltage to add, to the voltage correction value, a value obtained by delaying the voltage correction value by one period of the inverter output voltage to prepare a reference correction value to correct the reference voltage by the reference correction value, thus to prepare a volatge command for control of the inverter. The voltage control based on the reference correction value is carried out in a feed-forward manner, thus making it possible to effectively eliminate voltage distortion appearing periodically in synchronization with the output voltage.
