Abstract: Partial element equivalent circuit (PEEC) method is applied in this paper to establish the equivalent circuit of a simplified physical model consisting of two conductors based on the structural features of practical high-capacity power electronic converters, and its high frequency coupling characteristics are analyzed by simulation. The feasibility is explored that PEEC method is used to quantitatively analyze the electromagnetic interference problems concerning the conductors of different sizes and various layouts in a high-capacity converter.
