    • To suppress a DC component in AC power in a power converter for converting DC power to AC power. DC power is converted to AC power by a converter 2, and the AC power is supplied to output terminals u1 and u2 via an inductor 3. The converter 2 is controlled based on an error Δ(t) between an output current iP(t) outputted from the converter 2 and a target current j(t) outputted from a target current generation means 110 as a target value for the output current iP(t), and a DC component VD in an output terminal voltage v (t) is detected by a voltage detection means 18. A DC component ID is suppressed by correcting a target current j(t) by a DC component suppression means 8. Also, a DC component in the AC power is suppressed to prevent biased magnification of a transformer 4 by calculating a correction amount jh(t) for correcting the target current j(t) from the difference between a first instantaneous value d1 of a load current is(t) flowing to a load 4 at a first time point t1 and a second instantaneous value d2 of the load current is(t) at a second time point t2 that is a half cycle after the first time point to correct the target current j(t).
