A Novel Electro Magnetic Interference (EMI) Filter to mitigate Electro Magnetic Interference in a Zero Voltage Transition (ZVT) Technique based Boost Power Factor Correction Converter

In this paper, the issues of Electro Magnetic Interference (EMI) and its suppression in a Power Electronic System is presented. Different noises especially common mode noise and differential mode noise are analysed. A Boost PFC circuit employing ZVT technique is analysed and then an EMI filter is designed in the input side of PFC converter to protect the converter from the line side Electro magnetic Interferences. The prototype of proposed EMI filter is built for the PFC Converter.
