PROBLEM TO BE SOLVED: To reduce harmonics and radiation noise which are produced in an inverter. SOLUTION: This inverter controller is provided with on-pulse generating circuits 19, 23, 24, 25 which generate from reference voltage VUV on-pulses for keeping on either of those operating in pairs of a plurality of switching elements corresponding to the polarity, and conversion circuits 14, 15, 26, 27 which convert the reference voltage VUV into PWM pulses through PWM- modulating for turning on/off the others of the switching elements operating in pairs. |
