Abstract
In a power converter, in a period in which the polarities of output voltage and output current of a power converter differ, a pulse train voltage corresponding to a PWM signal is output by a first switching element and a second switching element being turned off, one element of a first switch element and a second switch element being turned on, and the other element being turned on and off based on an inverted signal of a PWM signal pulse width modulated in accordance with an output voltage command.
