Abstract This study investigates the EMC probabilities of a class-D amplifier including the effect of the decisions made in the design phase of the filter. The way the class-D amplifier works, generates potential EMC difficulties and is the reason for the study. The filter characteristics and EMC probabilities have been simulated, measured and discussed for four different filters, to show the impact of the combinations of different factors. It appears that the amplifier borrowed from Helio Audio including the implemented filter, complies with the international limits, defined in CE standard specifications for emission.
