Conducted emission analysis of electric nacelle anti ice system in aircraft

This paper describes the high frequency behaviour of an Electric Nacelle Anti Ice system (ENAI). In the high frequency range above 150kHz, conducted emissions have to be considered. A silicon-controlled rectifier (SCR) is the main source for conducted emissions. Simulation and measurements are implemented on the ENAI system for comparison and verification. Simulations were verified by measurements and were shown to be a good alternative to measurements to provide quick and reliable predictions, whilst interference in the measurement environment can cause errors.
