다이나믹 UPS의 성능시험을 위한 순시전압 변동 발생기

Instantaneous Voltage Disturbance Generator for the Performance Test of Dynamic UPS

This paper deals with a novel 3-phase power quality disturbance generator. The proposed generator can be applied to the performance that of custom power devices. Voltage sag, swell and outage are provided by the generator. The control scheme for the disturbance generation is simple, and hardware setup is cost effective, compared with conventional scheme. The operating principle of the generator is described and the usefulness verified through simulation with 10KVA power rating.
