L’impact des émissions électromagnétiques engendrées par des onduleurs dans un circuit électronique

Abstract

In recent decades, electromagnetic disturbances have become increasingly troublesome for electrical and/or electronic systems. The latter may also be a source of disturbance for neighbouring systems or other users of the same system. This gives rise to a discipline called EMC electromagnetic compatibility. From this definition, arise three poles of interest: the study of the sources of disturbances, the study of the linkages and, finally, the study of the impact of the disturbances on a «victim». In this brief, we have applied this problem in the high frequency domain, among the sources of electromagnetic disturbances; we can mention the DC-AC static converter. After modelling and simulation using LTspice software, the results obtained confirm the electromagnetic disturbance reality of the DC/AC static converter after the use of solutions such as LC and RSIL filters.
