PROBLEM TO BE SOLVED: To enhance efficiency of power conversion in a power converter 1 which converts AC power into DC power.SOLUTION: When performing charge control, a controller 50 turns two switching elements, out of switching elements Q1p-Q4p and Q5, on and performs switching control of one switching element. Consequently, ON voltage is generated as loss in three elements when the controller 50 performs charge control. In a power converter of prior art, four ON voltages are generated as loss when a diode bridge circuit performs full-wave rectification of the output voltage of an AC load. Consequently, the loss generated as the ON voltage can be reduced in a power converter 1 which converts AC power of an AC load 2 into DC power, and thereby efficiency of power conversion can be enhanced. |
