Abstract: In practice，the parasitic parameters have a non-negligible effect on the performance of invertercircuit. The influence of the main parasitic parameters on a new type of switched-coupled-inductor quasi-Z-sourceinverter was studied. By the reasonable analysis of the influence of the parasitic parameters（para...
