【The invention's effect】
The present invention includes an inductor belonging to an inductive load, an auxiliary winding magnetically linked with a main winding of the inductor, an auxiliary winding connected in series with an AC power supply, and an electromagnetic energy of the inductor. In this method, a current formed in the auxiliary winding at the time of discharge flows through the AC power supply in a forward direction to encourage power supply from the AC power supply. According to this, it is possible to efficiently energize the AC power supply by using the electromagnetic energy of the inductor belonging to the inductive load or the auxiliary winding, to increase the common angle, and to achieve a high power factor. In addition, since the existing inductor is used by adding an auxiliary winding, it is simple and inexpensive.
