ABSTRACT:
An inverter circuit having a bridge circuit comprising a plurality of switching elements connected in the form of a bridge for converting, into alternating current, a DC voltage produced by a DC voltage generating unit and which is received through a first switching circuit. The inverter circuit includes a pair of diodes and a spike absorbing capacitor which constitute a series network wherein the diodes are connected so as to be forward biased with respect to the DC voltage and the spike absorbing capacitor is connected between the diodes. The series network is connected in parallel with the bridge circuit and is connected to the DC voltage generating unit through the first switching circuit. The spike absorbing capacitor is connected in parallel with a smoothing capacitor of the DC voltage generating unit.
