Comparative evaluation of two models of UPQC for suitable interface to enhance power quality
TL;DR: In this paper, two control scheme models for UPQC, for enhancing PQ of sensitive non-linear loads, based on two different kinds of voltage compensation strategy, have been designed, which are termed as UPQQC-Q and UPQc-P. The effectiveness of the two control schemes is verified through extensive simulation using the software SABER.
Journal ArticleDOI
Investigation on the performance of UPQC-Q for voltage sag mitigation and power quality improvement at a critical load point
TL;DR: In this article, the authors proposed a new hybrid control scheme for the series compensator of the unified power quality conditioner (UPQC), which is termed as UPQC-Q. A PC-based new hybrid controller has been proposed and the performance of the new control scheme is verified in a laboratory prototype.
Journal ArticleDOI
Mixed-mode operation of boost switch-mode rectifier for wide range of load variations
TL;DR: In this article, a mixed-mode input current sensorless predictive current control at constant but two different switching frequencies for a single-phase boost type switch-mode rectifier (SMR) with single switch topology is proposed.
Proceedings ArticleDOI
Performance study of UPQC-Q for load compensation and voltage sag mitigation
TL;DR: In this article, the VA requirement issues of series and shunt compensators of UPQC-Q and its performance is verified in a laboratory prototype are discussed and typical experimental results are presented to confirm the validity of the theory.
Proceedings ArticleDOI
Experimental investigation of performance of a single phase UPQC for voltage sensitive and non-linear loads
TL;DR: In this paper, a unified power quality conditioner (UPQC) is proposed to protect the consumer at the load end from supply voltage sag, and provide unity power factor condition at the utility for different values of load power factor.
