| Abstract |
EMC compliance of TRIAC based dimmers is ensured through a bulky mains filter,
while it is usually performed through waveform shaping in insulated gate device based dimmers. This
last method allows to reduce the size of the system and, therefore, to implement wall-box dimmers. In
such a system switching waveforms achieving low EMI and acceptable power losses is of major
concern. The commonly used driving strategy (R-C network drive) could ensure a good ratio between
emitted interferences and switching losses. However experiments presented here show its over
sensitivity to changes in power device parameters. The study of the optimum gate voltages and
currents shows the gate current driving strategy as the more stable under power device parameter
changes. |
