Abstract
The 9-switch power converter can provide two sets of output terminals like the conventional back-to-back power converter. In this paper, the unified power quality conditioner (UPQC) is developed by using the 9-switch power converter with the enhanced repetitive controller (RC). The proposed 9-switch UPQC can mitigate concurrently harmonic current and voltage problems together with voltage sag/swell issues. And also, the switching loss is reduced significantly by using the discontinuous modulation strategy for the 9-switch UPQC. The characteristics of the proposed 9-switch UPQC are evaluated by simulation, and its superior performance is verified.
