面向无传感器三相四桥臂模块化多电平变换器的有限电平状态模型预测控制

This letter focuses on a finite-level-state model predictive control strategy for sensorless three-phase four-arm modular multilevel converter (MMC). The aim of this letter is to enhance the reliability of the whole system under the arm and sensor fault conditions. First, a three-phase four-arm MMC topology, which has a good potential to further improve the fault tolerance ability of the MMC, is p...
