Recent advances in common mode voltage mitigation techniques based on MPC

摘要

Model Predictive Control (MPC) is a powerful and robust strategy used to control power inverters. Common mode voltage (CMV) is a known source of problems in many inverter applications. The aim of this paper is to present and discuss the latest contributions in the area of CMV mitigation, with a focus on MPC-based strategies. The paper reviews the most common inverter topologies, including two-level (standard and modified) and three-level inverters, provides background of CMV generation and outlines opportunities and limitations for CMV mitigation, for each topology. The paper presents an extensive overview of the recent work on CMV mitigation, and outlines future scope for the MPC-based solutions of the CMV problem.
