The high switching frequencies of power converters always lead to severe radiated EMI. The modeling and analysis of the converter with undesired antenna such as input/output cables are very important for the research on radiation. This paper first develops the model for undesired antenna in converters and discusses its relationship with the radiated power. Then the antenna's interaction with converter...
This paper developed models for DM electromagnetic interference (EMI) input filters in AC-DC converters. The models are developed based on the circuit structures and control configurations. The models are developed for feedback, feedforward, feedforward-feedback and feedback-feedforward configurations. The closed loop gains are derived respectively. Based on the closed loop gain models, the open loop...
