From the past few decades, the increased usage of non-conventional energy sources and nonlinear loads alarmed the researchers more concern about the power quality (PQ). Distribution static compensator (DSTATCOM) is voltage source inverter (VSI)-based shunt compensating custom power devices (CPD) used for current harmonic mitigation and also for reactive power compensation. The features of traditional multilevel inverters at high levels motivated the researchers to implement reduced switch topologies (RST) as they aim for reduction in cost, volume and to improve reliability of the system. This paper proposes a five-level RST-based DSTATCOM, which reduces the switch count to 33% compared to conventional multilevel converters. %THDs of five-level diode-clamped converter (DCC) and the proposed RST-based DSTATCOMs under same loading conditions are compared to show the potency of the converter. All the simulations will be carried out in MATLAB/Simulink software.
