Abstract
A circulating current of a cycloconverter in each phase is distributed and controlled in such a way that a circulating current in a phase having a large absolute value of a load current is small, and the circulating current of a phase having a small absolute value of the load current is large. Therefore, the reactive power is so compensated that the sum of lagged reactive powers of the phases and advanced reactive power of a phase advancing capacitor cancel out each other.
