| Abstract: | Taking NPC 3-level inverter as an example, this paper studies the method of extracting composite compound bus bar port parameter matrix and building composite compound busbar multi-port circuit model. The busbar multi-port model is used to build a NPC 3-level inverse inverter simulation system. Based on the principle of the formation of midpoint current and the shock resonance mechanism, the influence on midpoint current of the stray parameters of the inverter for midpoint current is analyzed. The results of the experiments demonstrate the reliability and validity of the simulation, which means this method can be used in parameter calculation and optimal design of compound busbar. |
