| Abstract |
The high frequency electromagnetic perturbations emitted by a static converter can be reduced by
different methods : adding filters and shieldings is the most common one, decreasing dV/dt and dI/dt
with soft switching techniques [1] is another solution. Gate drive control is also a valuable solution
[2], [3]. The focus of this paper concerns this late point. It has been noticed that high frequency
perturbations (range 1-30MHz) are entirely determined by the switching transients [4]. So an
improved gate drive has been developed to control accurately the current shape during switching, in
order to get a hardly decreasing perturbation spectrum. |
