An inverter unit includes a DC power source, an inverter circuit having two or more pairs of switching elements which are connected in parallel to the DC power source, so that a DC voltage of the DC power source is converted into a pulse train-like, pseudo-AC voltage output from the inverter circuit, and a PWM generator connected to the inverter circuit for adjusting the pseudo-AC voltage by pulse width modulation. Further, the inverter unit includes a voltmeter for detecting an actual, output voltage which is output from the inverter circuit, and a duty cycle controller for controlling an output duty cycle, so that the detected, actual, output voltage becomes a target output voltage. In this inverter unit, a desirable, output voltage may be obtained stably and accurately even if a voltage of a power source fluctuates.
An inverter unit comprising a DC power source, an inverter circuit having a plurality of pairs of switching elements, in each pair of which the switching elements are coupled in series, and which pairs of switching elements are connected in parallel to said DC power source, so that a DC voltage of said DC power source is converted into a pulse train-like, pseudo-AC voltage output from said inverter circuit, and a PWM generator connected to said inverter circuit and capable of adjusting said pseudo-AC voltage by pulse width modulation, said inverter unit comprising:
