Abstract

Voltage sags have become a very critical power quality issue in recent years. To improve the quality and reliability of electric power, fast solid-state transfer switch (SSTS) based on thyristors can utilize the dual power feeders to achieve fast transfer and protect sensitive loads against voltage sags. Conventional SSTS may require more than a quarter cycle to complete the transfer process. In this paper, starting from the simplicity of conventional SSTS topology, finally an improved topology has been designed in this paper. The proposed system can greatly reduce the circuit hardware costs and raise transfer speed. Simulation results are performed to validate the excellent performance.
