6 Summary

This application note focuses on showcasing three solutions that can reduce radiated electromagnetic interferences. The proposed solutions are backed up by measured data obtained in anechoic chambers, under similar measurement conditions as recommended by the CISPR standards. While the solutions described in the report show to improve EMI performance, it is worth keeping in mind that they alone cannot be a guarantee for meeting the required standards. When dealing with EMI, the auxiliaries, the power supply, the load will also have an effect over the final result and their impact needs to be taken into account.
