<P>PROBLEM TO BE SOLVED: To provide an inverter device which carries a single operation detecting method which can reduce a loss to be consumed by an inductive load generated due to the cause of a harmonic current with good single operation detecting sensitivity by suppressing the current distortion factor of an output current with small harmonic component of the output current even if a dead zone region is reduced to raise the single operation detecting sensitivity. <P>SOLUTION: The inverter device includes a current distortion giving means 13 for giving a current distortion in which the frequency of the inverter output current accompanies discontinuous frequency change in the frequency of the inverter output current with continuous displacement or phase of the inverter output current in the peak point of the inverter output and a predetermined zone near it to generate the change in the output frequency of the inverter device 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
