A Study on the Compensation of Reactive Power by III, IV Quadrant Phase Controlled Rectifier

III, IV상한 위상제어정류기에 의한 무효전력 보상에 관한 연구

This paper describes the method of operating the phase controlled rectifier by controlling the firing angle in III, IV quadrant to absorb the lrading reactive power and of improving the waveform of ac current by driving dual converter. The system is intended to compensate the reactive power for any lagging load. Also, by the above method this paper enables us to improve the power factor and waveform referred to the source current and the dc output voltage in the converter.
