Abstract

A current-mode control technique with output filter inductor-current instantaneously controlled is proposed for the voltage-source inverter of uninterruptible power supplies (UPSs). This technique shows good dynamic response, high stability and current limiting in the case of load short. Small-signal analysis, parameter design simulation and experimental results are given in this paper
