Abstract
In an inverter apparatus for converting a direct current to an intermittent current by a converter configured by parallel-connected plural pairs of serially-coupled switching elements, resistance loads are connected across output terminals of the converter and a positive terminal or a negative terminal of a direct current source, and a direct current output can be supplied to the resistance loads from the inverter apparatus by controlling the converter at a low frequency.
