<p>A power conversion equipment or apparatus includes an AC/DC conversion circuit which rectifies and converts an alternating current power source to a direct current, and a DC/AC conversion circuit which converts the direct current to a high frequency three-phase alternating current voltage having 3N pulses times a fundamental wave frequency in a half cycle, the fundamental wave frequency being higher than the frequency of the alternating current power source. The power conversion equipment also includes a three-phase high frequency transformer having a primary winding that is connected to the output of the DC/AC conversion circuit, a rectifier circuit which rectifies a secondary winding voltage of the three-phase high frequency transformer, and a filter circuit connected to the direct current output of the rectifier circuit.</p> |
