A Study on the Controller for Reducing of In-Rush Current of Inductive Load

유도성 부하의 돌입전류저감을 위한 제어기에 관한 연구

This paper presents a new method to reducing inrush current and energy saving of capacitor starting single-phase induction motor used in air-conditioner. It can be obtained that proposed system is low cost and small size as compared with other controller. Experiments are focused on a capacitor starting single-phase induction motor. The optimal power saving and in-rush current limiting by phase angle control are verified by experimental results. Also, auxiliary winding was controlled by electronic starting switch.
