Purpose Votage source converter (VSC) based or current source converter (CSC) based shunt active power filter (SAPF)? It is the main question in harmonic elimination project using SAPF.This paper presents some criteria based on which the designer can decide which type of filter is more suitable for implementation of the project according to the nature and characteristics of the project. Design/methodology/approach Owing to the importance of cost and power losses criteria, relevant equations will be formulated and comparative analysis will be carried out between conventional structures based on CSC or VSC. For validation of analyses, simulation results have been studied in the MATLAB–SIMULINK environment. Findings Simulation results have examined two important criteria of power losses and costs. Although the results show the superiority of VSSAPF to CSSAPF in both criteria, this comparison is performed in a general and conventional condition. Using third-order filters of inductive-capacitive-inductive (LCL) type in VSSAPF, using insulated-gate bipolar transistor (IGBT) with reverse-voltage blocking ability in CSSAPF, which eliminates the need to use series diodes, and the use of superconducting technology in the DC-side endpoint in CSSAPF, not only reduce the difference of cost and losses in two schemes but also may lead to the lower costs and losses in CSSAPF than VSSAPF. Originality/value This paper is the result of many years working on active power filter and can be useful for engineers who are engaged in industrial projects.

“…At the same project, AC inductance of VSSAPF is more than that of CSSAPF (Zafari and Jazaeri, 2017a, 2017b). Also, according to Bilgin and Ermis (2010), as the inductance is directly related to the square of the number of turns, increase of inductance leads to increase of resistant, especially in air core inductors.…”

“…Passive elements which are small in size and low in weight than conventional APF are used in converters to find frequency of switching in both the converters. The unity power factor (UPF) control technique 7,8 makes the source to view the load and compensator as a resistance. In this, the current from source and point of common coupling (pcc) should follow each and are to be in phase with each other.…”

The increased use of electronics for control and use of nonlinear type loads by consumers in the present power system network are injecting harmonics into the power signal, due to which the power quality issue has become more challenge for the present researchers.In this work, the reduced order generalized integrator (ROGI) and fuzzy logic control (FLC) are collectively used to reduce the current harmonics in the power system. FLC-SVM technique is used to maintain the process of SAF-Shunt active filter with fixed switching frequency. This proposed control technique consists of control loop for current to have fast and effective control. The Proportional Resonant controller is used to have control on voltage for a slow and effective control process which is also used to compensate reactive power. The shunt active filter is designed with the help of ROGI by integrating PI controller for fuzzy-based SVM to reduce the current harmonics on the load side. The results are achieved in MATLAB/SIMULINK software.
