| Abstract |
In this paper a new control strategy with capacitor voltage differential feedback for the single-phase voltage source UPS inverter is introduced and analyzed. In this control scheme, only the capacitor voltage needed to be sensed as a control variable. Except for the basic features of most feedback control strategy, the scheme offers many features that are attractive to the UPS applications such as lower content of harmonics and fast dynamic response. A 5kVA UPS system under the proposed control scheme is provided to verify all of these features |
