Abstract

Xingkang Xue*

This review explores a novel voltage sensorless estimation method for Modular Multilevel Converters (MMCs) utilizing a Model Predictive Control (MPC) strategy. The approach aims to enhance the efficiency and reliability of MMCs, which are crucial in High-Voltage Direct Current (HVDC) transmission systems and renewable energy applications. By eliminating the need for voltage sensors, the proposed method reduces system complexity and cost while maintaining high performance. This article delves into the principles of MMCs, the challenges associated with voltage sensing, the fundamentals of MPC and the innovative aspects of the sensorless estimation method.
