Tarateeraseth V. Derivation of insertion loss equations for EMI filter design. Proceedings of the IASTED Asian Conference on Power and Energy Systems, AsiaPES 2012. Vol , No. (2012), p.326-333. doi:10.2316/P.2012.768-074 Retrieved from: https://hdl.handle.net/20.500.14740/7033
In this paper, the derivation of insertion loss equations for designing EMI filters used in power electronic applications e.g. switched-mode power supplies is proposed. Classical passive EMI filter topologies i.e. LC-, CL-, π-configurations are derived. With the provided insertion loss equations and the known magnitude and phase of the terminated noise source and load impedances, the EMI filter can be optimally and systematically designed.
