<P>PROBLEM TO BE SOLVED: To suppress a DC component included in an AC component in a power converter for converting DC power into AC power. <P>SOLUTION: The DC power is converted into the AC power by the converter 2, and supplied to output terminals u1, u2 through an inductor 3. The converter 2 is controlled based on an error Δ(t) between an output current i<SB>P</SB>(t) outputted from the converter 2 and a target current j(t) as a target of the output current i<SB>P</SB>(t) outputted from a target current generating means 110. The DC component I<SB>D</SB>is suppressed by detecting the DC component V<SB>D</SB>included in a voltage v(t) across the output terminals by a voltage detecting means 18, and correcting the target current j(t) by a DC component suppressing means 8. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
