In this article, Asymmetrical voltage source Multilevel Inverter based Transformerless Dynamic Voltage Compensator (ASMLI-TDVC) for load Voltage Quality (VQ) enrichment is proposed. The ASMLI-TDVC is controlled such that it compensates different levels of VQ problems with lesser Total Harmonic Distortion (THD). Synchronized voltage injection achieved through series transformer from traditional DVC leads to rise in the size of DVC and make system cumbersome. ASMLI based on less switch count topology is utilized for TDVC to overcome these aforementioned issues. Simulation studies of ASMLI-TDVC are carried out using Matlab Simulink software. Further, an experimental model is developed and tested in real-time using OP4500. Results prove that dynamic compensation for VQ improvement is achieved by ASMLITDVC. © 2020, Gazi Universitesi.
