ABSTRACT:
A reactive power control cycloconverter for three-phase AC is provided with a reactive power source coupled to power lines of the three-phase AC, a three-phase cycloconverter unit for converting three-phase input power from the power lines into three-phase output power, and a control circuit for controlling the flow of a circulating current according to a detected value of reactive power of the three-phase AC. The cycloconverter includes three power converters which are connected in a delta fashion so that the circulating current for compensating the reactive power of the three-phase AC is allowed to flow in a closed-loop of the delta-connection of the power converters.
