Análise das Emissões Eletromagnéticas em Conversores Chaveados em Regime Transitório

Abstract

The Current electromagnetic emissions standards, such as those produced by the CISPR committee, perform the radiated emission test of switched-mode converters only under a permanent operating regime. In this way, electromagnetic emissions generated during transients of starting or shutting down of these converters are not submitted to a control. These transients may cause electromagnetic interference issues, especially if the converters are electronic ballasts for lamps, which are usually present in a large number in the same environment and exposed to several daily cycles of
