| Abstract |
Nowadays, EMC standard compliance is part of the constraints that every electronic and
electrical system must fulfil. Power device switching is the main cause of conducted electromagnetic
interferences produced by power conversion systems. Studies and optimisations of switching
waveforms are therefore of major concern in power electronics. Several works deal with this subject.
They define relations between waveforms and conducted interferences. As a result, sinusoidal shaped
switching waveform is shown to be the optimal one. In order to understand how to achieve such a
waveform, the impact of MBS electrical parameters on switching waveforms should be investigated.
This paper presents a simple electrical representation of MBS during turn-on in a resistive or low
inductive load. Some conclusions on the influence of MBS electrical parameters on switching
waveforms are drawn from it. |
