Electromagnetic Compatibility Problems in Automotive Applications

This paper discuss electromagnetic compatibility problems in automotive applications where the voltage is controlled by pulse width modulation. Some proposed solutions are presented, and also the results are shown. In order to get a good measure of the efficiency of the different solutions, the radiated emissions from a system composed of a power electronic part with a DC/DC converter and a load are measured. The solutions that are tested are affecting both the hardware and the software of the setup. Also experiments where different solutions are combined are investigated.
