Abstract
An arrangement is provided a converter, an inverter, a smoothing condenser connected between the converter and the inverter, and reactors each connected between the connection point of each pair of IGBT switches of the converter and the output terminal of each phase of the AC power source. The converter has three pairs of IGBT switches for three phases that are serially connected to one another and connected in parallel to one another. First diodes are each connected in reversed polarity and in parallel to each IGBT switch. The inverter has three pairs of IGBT switches that are serially connected to one another and connected in parallel to one another. Each diode is connected in reversed polarity and in parallel to each IGBT switch.
