Model Predictive Control of Neutral Point Clamped Inverter with Reduced Switching Frequency

This paper proposes a novel model predictive control (MPC) algorithm with reduced switching frequency for Neutral Point Clamped (NPC) inverters. The proposed method can reduce the switching frequency through the optimization of switching sequences, while keeping the advantages of the conventional MPC method such as fast response and handling multiple constraints. The performance of this proposed method is verified by simulation results with a three-level NPC inverter. © 2019 The Korean Institute of Power Electronics (KIPE
