POWER CONVERTER AND INVERTER DEVICE EQUIPPED WITH SAME

摘要

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 switching element Q1 and switching element Q2 being turned off, one element of a switch element S1 and switch element S2 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.
