    • A power unit is provided which is capable of controlling a rise in voltage applied to each of thyristors constituting a cycloconverter even when the output voltage of the power unit undergoes a temporary sharp rise due to characteristics of a load connected thereto. Positive and negative converters of the cycloconverter are connected to three-phase output windings of a three-phase generator and connected in an antiparallel manner to each other for generating a single-phase alternating current to be supplied via a pair of output lines to the load. A firing angle control device causes the positive and negative converters to be alternately switched to operate every half a repetition period of the single-phase alternating current, to thereby cause the cycloconverter to generate the single-phase alternating current. A bridge rectifier is connected between the pair of output lines. An electric energy-storing capacitor circuit is connected to the output of the bridge rectifier, for storing the rectified output therein.
