“…The reduced switching devices may affect the compensation performance of UPQC. The half-bridge topology- based UPQC system can be found in [57], [83], [106], [150], [156]. Zhang et al [93] have considered a bidirectional two Hbridge dc/dc-isolated converter topology to isolate UPQC shunt and series inverters from each other.…”

This paper presents a comprehensive review on the unified power quality conditioner (UPQC) to enhance the electric power quality at distribution levels. This is intended to present a broad overview on the different possible UPQC system configurations for single-phase (two-wire) and three-phase (three-wire and four-wire) networks, different compensation approaches, and recent developments in the field. It is noticed that several researchers have used different names for the UPQC based on the unique function, task, application, or topology under consideration. Therefore, an acronymic list is developed and presented to highlight the distinguishing feature offered by a particular UPQC. In all 12 acronyms are listed, namely, UPQC-D, UPQC-DG, UPQC-I, UPQC-L, UPQC-MC, UPQC-MD, UPQC-ML, UPQC-P, UPQC-Q, UPQC-R, UPQC-S, and UPQC-VA m in . More than 150 papers on the topic are rigorously studied and meticulously classified to form these acronyms and are discussed in the paper.Index Terms-Active power filter (APF), harmonic compensation, power quality, reactive power compensation, unified power quality conditioner (UPQC), voltage sag and swell compensation.

“…A comprehensive overview of the topic about different topologies and control schemes of UPQC is provided in [11]. Full-bridge, half-bridge and three-leg topology are the main applications in singlephase UPQC [12][13][14]. Among all the three topologies, three-leg UPQC (TL-UPQC) is considered to possess high performance with reduced cost [15].…”

Control strategy for com-leg in single-phase transformerless three-leg Unified Power Quality Conditioner

Single-phase three-leg Unified Power Quality Conditioner (UPQC) is relatively a good choice for power quality compensation in low-power applications as it can achieve high performance with low cost. In this paper, a decoupling control method is proposed to eliminate the interaction between the series and shunt converters of the three-leg UPQC. In the proposed method, output voltage of the common leg is controlled proportional to the grid voltage and the proportional coefficient is optimized to ensure the compensation of both the series and shunt converter with lower DC-link voltage. Additionally, theoretical analysis and certain design criterions are provided in the paper. Simulation and experimental results are also presented to verify the feasibility and effectiveness of the proposed decoupling control method.
