| Abstract |
In bridge-leg power converters, delays between the logic command signals and the switching of the power devices (the delay in the interface and switches) storage and switching-time of the power device, may generate short circuit in the bridge-leg if not considered. The obvious solution is to introduce dead-time between the switching signals of top and bottom devices in a bridge-leg. This solution limits regulation and linearity of the modulation signal. Using practical examples, interactive switching strategies are analysed which optimise the delay-time between one device switching-off and the other switching-on. |
