Abstract
A power converter fixes, in one cycle of an alternating-current voltage output command, a gate pulse signal to always output a direct-current input positive side terminal voltage value of an inverter circuit in a period Xcentering on a phase angle θfor higher potential, fixes a gate pulse signal to always output a direct-current input negative side terminal voltage value of the inverter circuit in a period Xcentering on a phase angle θfor lower potential, and outputs a gate pulse signal in which a ratio of a period Y, which is obtained by excluding the periods Xand Xfrom a period between the phase angle θand the phase angle θ, and the first period X, and a ratio of a period Y, which is obtained by excluding the periods Xand Xfrom a period between the phase angle θand a phase angle θ+360 [deg].
