Abstract

PURPOSE: To keep current-control function by taking out any of phase advance or phase slow reactive power from the system by providing reactor between the system and variable voltage source for the regulation of the output voltage of variable voltage source.
CONSTITUTION: The power system 4 is through the reactor 5 to the inverter 6 as variable voltage source, and reactive power is regulated by changing the output voltage of the inverter. The reactive current detection circuit 53 compares phase advance and phase slow power from the current signal IQ and the voltage signal VA and detects the signal SI proportional to the magnitude of current, and the output therefrom, added to the reference signal Vref and voltage siglnal VA at the addition circuit 55 through the limitter circuit 54, controls the forward converter 8 through the gate amplifier I6 in case where the output current of the inverter exceeds the set value. Thus, the output currnt of the inverter to which is given power the forward converter can be controlled.
