Electromagnetic Interference (EMI) Characterization for Electric Vehicles (EVs) Hybrid Electric Vehicles (HEVs)

摘要

This paper proposes empirical strategies for characterizing the EMC features of EV/HEV drives. By a few quick measurements and minimum amount of numerical computations, the attributes of the equivalent noise sources and the distribution paths can be portrayed separately. As such, the traditionally sticky EMC problems are conceptually divided into two halves, which provides an easier view when dealing with them. To support this strategy, theoretical analysis and test procedures are detailed, and the approach is validated by test results. Thorough discussion is then followed to provide insightful observation, and a concise conclusion is appended to wrap up this paper.
