In recent years, reactive power controllers using power-electronics technology (Static Var Compensators) have been well researched and developed with a view to voltage control, power stabilization, power swing stabilization, power factor improvement, and suppression of voltage flicker. The remarkable characteristics of SVC are to make it possible to continuously control these properties, and to have quick response.The present paper deals with the SVC based upon reduced harmonics converter with tap changers. In addition to the foregoing characteristics, the SVC has some more ones given below:(1) This SVC, with the use of tap changers of interphase transformers, can make its main circuits so simplified.(2) SVC cuts harmonic current down into its non-fault level (3.3% distortion factor), so that it does not cause any practical problem.(3) The SVC so well responds that it makes the high-speed controlling of reactive power less than about 3Hz.(4) The SVC can control lead or lag reactive power itself, so that its whole system can be made compact and small-sized.
