Performance evaluation of frequencial behavior of Layout (PCB + Parts) of the electronic ballasts to fluorescent lighting in the electromagnetic interference (EMI) propagation

This article presents a study about the non-ideal and frequency dependent behavior of the set which constitutes the layout, that is, the Printed Circuit Board (PCB) linked to electro-electronic components in electronic ballasts for fluorescent lighting, related to the conducted disturbance at mains terminals (electromagnetic interference-EMI). The determination and experimental proof of PCB and some specific components non-ideal models are made and the results applied in order to obtain an answer concerning the EMI through a computational simulation. The results are discussed and compared with the EMI measurements and tests in an implemented prototype in a lab.
