Abstract
Numerous loads require the installation of load transformers for electrical isolation or voltage matching. When these loads are powered by a single-phase on-line UPS system, a high magnitude of transient inrush current is often observed due to the energizing of the load transformer. In this paper, we propose a novel single-phase on-line UPS system that eliminates the generation of inrush current while powering multiple load transformers. The performance of the proposed single-phase UPS system is endorsed by our experimental results obtained using a small laboratory-sized prototype.
