The aim of this paper is to identify an optimum control strategy of three-phase shunt active filters to minimize the total harmonic distortion factor of the supply current. A classical PIPI cascade control solution of the output current of the active filter and the voltage across the DC capacitor based on Modulus–Optimum criterion is taken into consideration. The control system operation has be...

This paper presents a control strategy for a Unified Power Quality Conditioner. This control strategy is used in three-phase three-wire systems. The UPQC device combines a shunt-active filter together with a series-active filter in a backto-back configuration, to simultaneously compensate the supply voltage and the load current. Previous works presented a control strategy for shunt-active filte...

This paper proposes a photovoltaic (PV) and battery interfaced series hybrid active power filter (SHAPF), which consists of series active power filter and an LC shunt passive filter. The main benefits of the proposed system provide the compensation against the voltage harmonics, current harmonics and voltage interruption for the whole day. A series active power filter (SAPF) demands a source of...

This paper proposes a three-phase four-wire currentcontrolled Voltage Source Inverter (CC-VSI) for both power quality improvement and PV energy extraction. For power quality improvement, the CC-VSI works as a grid current-controlling shunt active power filter to compensate for harmonic and reactive power of loads. Then, the PV array is coupled to the DC bus of the CC-VSI and supplies active pow...

The main objective of this paper is to develop and analyze the compensation characteristics of cascaded multilevel inverter based shunt hybrid active power filter by employing indirect cur...

This paper presents the analysis of series active power filter for reactive power compensation, load balancing, harmonic elimination, and neutral current eradication in three-phase four-wire power systems. Generally, the three-phase four-wire system is widely employed in distributing electric energy to several office building and manufacturing plants. In such systems, the third harmonic and its...

This paper provides an overview of differential single-phase inverter topologies with active power decoupling (APD) and their main control techniques. Owing to the advantage achieving APD without additional semiconductor devices, thus boosting reliability at a minimum cost, these have gained increasing interest, especially for small-scale photovoltaic applications. Therefore, in this study, we ...
