Abstract :
This paper describes a new sag-swell generator for the test of custom power devices such as UPS, DVR, DSTATCOM, SSTS, etc. The proposed scheme has good features of simple structure, high reliability, wide range of voltage sag and swell variation, and easy control. Outage, harmonic distortion, notches, and voltage unbalance also can be generated. The operation principle of the proposed scheme is described and the characteristics are analyzed through simulation. The usefulness of the scheme is verified through experiments.
