The Analysis of Bearing Current using Equivalent Circuit Parameters by FEM

FEM이 적용된 등가회로 파라미터에 의한 축전류 해석

This paper deals with the analysis of bearing current in H-bridge seven level multilevel inverter fed induction motor. In the previous researches utilized electromagnetic equations to derive the parasitic capacitance or measured capacitance parameters, but we used FEM to derive parasitic capacitances and defined the equivalent circuit parameters in our strategy. Then we compared suggested method with conventional method in 60 [Hz] no load condition.
