Summary:
Instead of combustion engine, electric drive becomes the main power source for pure electric and hybrid vehicles. For one thing, it?fs eco-friendly and economical. For another, it introduces nonnegligible electromagnetic interference that threaten the electromagnetic compatibility of the system. One way it affects is high-low coupling, where electromagnetic interference transfers from high voltage components to low voltage components by means of conduction and radiation. In R&D stage, high-low coupling attenuation need to be considered and evaluated. After system integration, measurement of high-low coupling need to be performed. In this paper, mechanism of high-low coupling is studied. Test method at both R&D stage and system integration stage is introduced. It will help engineers find the weak point of the system and provides suggestion for optimization.
