A power converter is provided with a pair of main circuit switching elements (5) wherein at least one switching elements (5) is composed of a FET having a diode (6) connected in reverse-parallel; a means (13c) for generating a PWM basic signal; a delay means (13d) for delaying the on-signal of the PWM basic signal a prescribed time; a switching signal correcting means (13e) which compares the delay time with the on-time of the PWM basic signal, and maintains the on-status of the other switching element when the on-time of the PWM basic signal is shorter than the delay time; and a reverse voltage applying means (7) for applying a reverse voltage to the diode (6).
