Patent ID: 7184282

Claim:
A single-phase power conversion device which produces single-phase AC power from DC power source and supplies the power to a load connected to output terminals thereof, comprising: a converter for converting the DC power from the DC power source to single-phase AC power; an inductor connected to the AC side of the converter; a current detection means for detecting an output current flowing through the inductor; a voltage detection means for detecting an output terminal voltage applied across the output terminals; a target current generation means for generating a target current as a target value for the output current; and a converter control means for pulse width modulation control of the converter based on an error between the output current and the target current; wherein the target current generation means has a DC component suppression means for suppressing a DC component in the single-phase AC power by amplifying an integral of the output terminal voltage detected by the voltage detection means and using the amplified integral to correct the target current.
