Abstract
Gallium Nitride (GaN)-based converters have emerged as a promising technology to increase the efficiency and power density of power electronic systems in electric vehicles (EVs). However, the integration of GaN semiconductor devices introduces challenges regarding electromagnetic interference (EMI). This work focusses on EMI measurements and on exploring the relationship between defined parameters such as output current or switching frequency and conducted emissions (CE) in converters with GaN switches. Moreover, the relationship between the switching transients of the GaN-FETs and the interference frequency range is examined and the challenges of using GaN-based converters in EVs related to EMI are discussed.
