Abstract

PURPOSE:To reduce the distortion of an inverter output voltage by correcting a voltage vector command and its generation phase, so that an error vector becomes smaller, at the time of applying a pulse width limit. CONSTITUTION:A pulse width limiter 4 judges from a voltage vector group and a time for generating each voltage vector obtained by PWM computing element 2 whether a pulse width depends on limiting conditions of each phase switching elements of an inverter. When the pulse width does not depend on said limiting conditions, the output of said PWM computing element 2 is sent as it is to a PWM signal output unit 5. When the pulse width depends on said conditions, a momentary voltage vector command value or its phase is corrected in the direction of reducing the output distortion of said inverter.
