Radiated emissions affect a power converter’s EMI signature at high frequencies [1]. The upper test frequency for radiated tests extends to 1GHz or higher depending on the specification, and EMC emission and immunity standards are developed to specify terms, measurement methods, limits for conducted and radiated electromagnetic emissions and level of minimum immunity Electromagnetic interference issues are associated with high-speed switching of power converters. EMI modeling is an essential tool to study and control the EMI emission,
