<p>The present invention suppresses bias magnetism without deteriorating control responsiveness or stability of output voltages. This power conversion apparatus is provided with: a switching circuit, which applies voltages in one direction and the reverse direction to a primary winding wire of a transformer by sequentially switching switching elements, each of which is configured from an upper arm and a lower arm; a rectifying circuit, which rectifies an alternating current output generated from a secondary winding wire of the transformer; and a control apparatus that on/off controls the switching elements. The control apparatus is provided with a detector that detects bias magnetism in the transformer, and corresponding to an output of the detector, the control apparatus increases, by a predetermined quantity, an application time of a voltage to be applied in the one direction, and reduces, by the predetermined quantity, an application time of a voltage to be applied in the reverse direction, thereby reducing the bias magnetism.</p> |
