Abstract

Abstract:

The on-board EMC test system is an important equipment for testing the EMI performance of electric drive system of new energy vehicles. To optimize self-developed on-load EMC test system in China and promote the research of EMI characteristics of electric drive system， this study self-developed the first on-load EMC test system for electric drive through wall that can fully meet the CISPR 25-2016 test standards. By analyzing the demand of EMC test， the design scheme of EMC test system is proposed. Then， a three-dimensional model of the EMC test system is established and electromagnetic simulation is carried out， while the interference sources and shielding integrity of the system are analyzed， so as to guarantee the EMC compatibility of the designed system. Finally， by building the EMC test system， the accuracy and reliability of the system are further improved after analysis and optimization based on the bottom noise test.

Key words: electric drive system, electromagnetic compatibility, test system, design and optimization
