Recent developments of electric cars have shown significantly more problems with EMC compared to the established 12V grid. Especially the component testing procedure does not work as well in the high voltage grid. This paper works out the main reason for it, the low losses for high frequency resonances between components. Solutions are discussed, which are the virtual design of the grid in a simulator, the passivation of components by lossy filters and building up a complete HV grid in advance. The virtual design is finally demonstrated on several examples.
