Modeling and Prediction of Common-Mode Conducted Noise in Boost Converter with Terminal Port Theory
説明
This paper presents a common-mode conducted modeling method with terminal port theory and applied it to boost converter. With no need to measure and analyze the voltage between MOSFET switch directly, this method can obtain the equivalent noise source accurately by utilizing the common-mode current. Then an equivalent common mode model is proposed based on the boost converter according to the features of its noise propagation loop. The accuracy of impedance measurement has also been improved by utilizing interpolation method. In order to examine the validity and robustness of this model, several kinds of filter circuits have been employed and the prediction results show conformability with the experimental results.
