Abstract :
Model predictive control has become a promising control technology in power converter, because of the good dynamic response and accurate current tracking capability. This paper mainly analyzes and verifies the model predictive current control of a three-phase cascaded H-bridge multilevel converter. In order to solve shortcomings of the large amount of computation and difficult to control, an improved method is presented to reduce computation considering adjacent levels. And the system performance is not affected. The control algorithm is validated by the simulation results of a seven-level inverter.
