Abstract
Green energy and clean power are the recent trends of modern power distribution networks (PDN). In recent years, great attention has been focused on T type inverters due to their advantages over conventional voltage source inverters (VSI), such as fault-tolerant, overload capability, less total harmonic distortion (THD), better output waveform and high efficiency. An inductor coupled T type (IC-T type) inverter-based distribution static compensator (DSTATCOM) is built for active power filtering of 3-phase 3-wire PDN connected nonlinear load in this paper. The proposed topology is composed of three inductors connected between the VSI and common source. The proposed PDN is obstructed by the DSTATCOM using icos𝜙 control algorithm for the inverter DC link voltage reduction, filter inductor rating minimization, decreasing the switching stress, increasing the life span of an inverter, reliable operation, stress balancing, loss reduction and increase in efficiency. Apart from these, other improvements such as power factor (PF) correction, better voltage regulation, harmonics reduction and load balancing are obtained. The efficacy of the IC-T type inverter in different loading scenarios is justified using MATLAB/Simulink software captivating in reflection of the IEEE-514-2017 and IEC- 61000-1-3 benchmark.
