T-NPC three-level inverters have found extensive application in the field of medium-power and high-power gen-erations,and facilitated greatly the improvement of energy conversion efficiency.The present work studied a new-type of topological structure for power electronic transformers based on the T-NPC three-level inverter.By substituting two-level inverter in conventional PETs with the T-NPC three-level inverter,the proposed control strategy was expected to suppress harmonics and reduce losses.The proposed control strategy was preliminarily indicated feasible and effective through a MATLAB/Simulink simulative experiment.
