Electric energy sector faces growing power quality (PQ) issues due to widespread industrial automation and the installation of distributed generation systems employing power electronic converters. This paper presents enhanced approach for PQ improvement using a Unified Power Quality Conditioner (UPQC) with reduced switch inverter topologies, specifically focusing on ten-switch and nine-switch configurations. The proposed topologies aim to improve semiconductor utilization while maintaining full voltage and current compensation capabilities. Conventional three-phase UPQC systems typically employ a 12-switch configuration using two six-switch voltage source inverters (VSIs) interfaced back-to-back, leading to underutilization of semiconductor devices under specific operating conditions. To overcome this limitation, the paper investigates and develops ten-switch and nine-switch UPQC topologies that reduce the overall switch count without increasing the switch volt-ampere (VA) rating, while retaining the compensation performance of the traditional 12-switch UPQC. A comprehensive analytical comparison of the proposed topologies is presented, evaluating semiconductor utilization, control complexity, and power quality performance. Extensive simulation studies using MATLAB/SIMULINK and experimental validation demonstrate the effectiveness of the proposed ten-switch and nine-switch UPQC configurations in mitigating voltage sags/swells, current harmonics, and reactive power issues, thereby enhancing power quality with reduced hardware complexity and cost.
