ABSTRACT:
Power is fed to a plurality of loads by a respective plurality of circulating current type cycloconverters connected to an ac power supply. A power compensating capacitor common to the cycloconverters is provided at the ac power receiving-end to deliver a leading reactive power to the ac power supply. Further, each cycloconverter is provided with means for delivering a circulating current and means for delivering a circulating current command value to the circulating current control means. A lagging reactive power corresponding to the leading reactive power by the power factor compensating capacitor is delivered to the ac power supply. The power factor compensating capacitor may be configured so that its capacity is variable by changing the number of stages connected. In addition, the circulating current command value may vary depending upon the peak value of the current flowing in each cycloconverter.
