In this paper, the effects of parasitic couplings in electromagnetic interference (EMI) filters are investigated using an equivalent circuit analysis and experiments. The investigated filter has the C-L-C filter structure which is composed of foil capacitors, feedthrough capacitors, and a toroidal inductor. The parasitic couplings between input capacitors and output capacitors increase the transfer...
Power electronic components such as busbars, capacitors, and inductors are positioned close to each other when designing a high power density converter. Therefore, the internal near field couplings between these components should be considered when designing a low electromagnetic interference (EMI) converter. In this paper, we propose a new frequency domain model for simulation of EMI in power electronic...
When designing an Electromagnetic interference (EMI) filter for power electronic converters, we should consider the shielding performance against the external near field coupling to the EMI filter as well as the attenuation performance. In this paper, we studied the validity of the Finite Element Method (FEM) simulation of the EMI filter for predicting the shielding performance before a trial manufacture...
