Design of Differential-Mode Input Filters for DC-DC Switching Regulators
This paper discusses a novel approach to EMI filter design, based on parametric charts that allow to achieve optimal damping by matching the winding resistance of the damping inductor with the ratio between filter and damping inductances. The proposed approach simplifies the identification of the smallest commercial components complying with attenuation and efficiency requirements. Experimental results presented in the paper validate the proposed model and design method
Optimum design of differential-mode input filters for DC-DC switching regulators
This paper discusses a design procedure of damped differential-mode input filters for DC-DC switching regulators, allowing to minimize the size of the filter and damping inductors and of the filter capacitors. The proposed approach simplifies the identification of the smallest commercial components complying with noise attenuation, stability and efficiency requirements, while ensuring optimal damping of the filter. The experimental results presented in the paper validate the proposed design method
