To address the issue of sub-module number errorscaused by harmonics based on nearest level modulation (NLM) when the voltage level is increasing in a modular multilevel matrix converter (M3C), a mathematical model for M3C was established. The operating principle for M3C based on NLM was analyzed, and an optimized sampling NLM strategy was proposed. Asimulation model of M3C consisting of 20 sub-modules was constructed based on MATLAB/Simulink, and a low-power experimental prototype of M3C was also built. Results verified the feasibility and effectiveness of the proposed method for harmonic suppression.
