Abstract
The paper describes the challenges of testing high voltage systems of modern electric and hybrid vehicles for electromagnetic compatibility (EMC). It introduces a new test set-up to assure EMC testing satisfying the relevant standards and specifications, while the system operates in its real condition. This set-up is already introduced in the international standard committee and is described in a committee draft for vote [1]. The set-up allows the evaluation of automotive high voltage applications such as powertrains on component level. This ensures the EMC validation at an early state of development without a vehicle. Additionally the measurement of the coupling factor between high voltage and low voltage level is presented, which is significant to define EMC limits for high power and high voltage components and systems. All the measurements were carried out in a ISO 17025 certified EMC lab with test equipment which is usually used for EMC measurements due to CISPR, and ISO EMC standards. First measurements were already published in 2013 [2] and 2015 [3].
