Abstract

The radiated emission (RE) certification is a major challenge to the development of a telecommunication (telecom) power supply. This challenge makes the accurate prediction of far field radiation important. This work proposes a novel far field RE prediction method combines the common mode (CM) voltage driving sources and their corresponding radiation transfer functions. The CM voltage driving sources of an AC/DC telecom power supply are identified and measured, and the amplitude-frequency curves of radiation transfer functions are gotten by electromagnetic numerical simulations. Then, the far field RE of a 4 kW telecom power supply with complex test layout is predicted and verified by experiment results in a 10 m semi-anechoic chamber. The main influence factors of radiated emission are subsequently analyzed too, which provide a theoretical basis for suppressing far field radiation.
