Abstract
The aim of the study is the analysis of EMC disturbances production from a power supply unit for a radar subset (Power amplifiers, transmitter and reception (T/R) modules, synthesizers. The front stage of the power circuit is made of a power factor corrector (PFC). The output circuit is a BUCK converter insulated from the PFC by means of a transformer. Both PFC and output circuits, required the analysis of critical frequencies appearance facing the EMC standard for such application. For a given device the first step of modelling can be achieved by identification of the circuits' active loops. This is aimed to investigate EMC by means of simulation. The near field analysis and Fourier transform computation can give the relevant parameters values and the deterministic way to investigate or cancel the disturbances. This can give a tool of good design process for future devices.
