In this paper a planar inductor based resonant circuit is designed for zero-current switching (ZCS) buck converter. The electromagnetic behavior of the design is analyzed by finite element (FE) methods for EMI interactions. A high frequency model for conducted EMI in the resonant circuit is obtained. To suppress the conducted EMI in the circuit, a method based on the resonant circuit impedance control is proposed. All the results are compared to conventional circuits and improvement in responses were observed and verified through simulation and laboratory experimentation.
