In this paper, we analyze the behaviour of a switched mode power supply (SMPS) regarding the radiated magnetic nearfield through an initial understanding of the electrical working of the converter, particularly during switchings. We propose a method based on impedance analysis at each state of the converter in order to predict the resonances of currents and/or voltages in the SMPS at the origin of the magnetic radiated near-field.
