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 X1 centering on a phase angle &thetas;1 for 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 X2 centering on a phase angle &thetas;2 for lower potential, and outputs a gate pulse signal in which a ratio of a period Y1, which is obtained by excluding the periods X1 and X2 from a period between the phase angle &thetas;1 and the phase angle &thetas;2, and the first period X1, and a ratio of a period Y2, which is obtained by excluding the periods X1 and X2 from a period between the phase angle &thetas;2 and a phase angle &thetas;1+360 [deg]. |
