Abstract :
This work describes high frequency EMI interference problems in linear power systems, in particular in a low frequency power amplifier. A complete industrial prototype with special shielding and filtering has been designed and mounted, where several techniques to suppress conducted EMI interference have been included, showing an excellent performance in suppression of these kinds of interference. The importance of the classical, not regulated, power supply in the interference propagation problem is described in this paper
