Electromagnetic Compatibility Problems in Automotive Applications

In English 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.
