Abstract
The development of electric vehicles has greatly increased the degree of automotive electronics, but in its high-voltage components (such as motor controllers, power batteries, etc.), it is impossible to completely isolate the high voltage circuit relative to the low voltage circuit, so that it is worth to study the attenuation characteristic of coupling path of high and low voltage circuits.This article, based on the drive motor controller in an electric vehicle by using vector network analyzer, analyzed high and low voltage coupling attenuation test method and discussed different grounding methods for comparison.Through analysis and comparison, it is concluded that the attenuation test is more accurate by using the network analyzer and the flat copper conductor grounding method, which helps to determine the high and low voltage coupling of the electric vehicle high voltage products, and better improve the electromagnetic compatibility (EMC) characteristics of the electric vehicle.关键词
