전압새그 발생시의 위상각 점프 구현 기능을 갖는 전압변동 발생기

This paper describes a voltage disturbance generator with phase jump function. The generator provides the function of voltage sag, unbalance, outage and phase jump of the output voltage. The proposed generator has good features of high reliability, low cost, simple structure, high efficiency and easy implementation. The circuit analysis and operating principle of the proposed scheme are described in each operating mode. The characteristics of the voltage in each mode are analyzed, and the usefulness of the scheme is verified through simulations.
