A power converter including: a transformer in which first and second voltages are induced; a full-bridge circuit including parallel-connected first and second arms each including series-connected FETs; and a control circuit, wherein, within a given time period for which a voltage V2 is the first voltage, the control circuit performs control so that FETs in at least one arm are on for an on time period, and, when Pon, PX, PS,α, andβrespectively denote a duration of the on time period, a duration of the given time period, a duration of a time period from the end of the on time period to a time point of transition from the first to second voltage, a rise time of a body diode of each FET, and a fall time of the body diode, Pon>(β/α)PS, 0≰PS<α, and Pon+PS≰PX are satisfied. |
