Zusammenfassung:UPS is largely divided into passive-standby, line-interactive, and double-conversion types. In general, a double-conversion type is used at a site requiring a high reliability. The main function of the double-conversion UPS is providing the constant voltage, constant frequency, regardless of the linear or non-linear load and variation of the load. In this paper, the robust controller of the single phase double-conversion UPS is designed and its performance is verified by both simulations and experimentation.
