| Abstract |
New automotive applications require high-frequency switching of high currents. This results in
considerable voltage-drops on the device and circuit parasitic inductance. Basing on the example of a
synchronous-rectified buck-converter, this paper presents a simulative and experimental analysis of such
effects and their influence on the nominal circuit behaviour.
The results show in particular that increased turn-on and turn-off times with larger power dissipation
are to be observed and that unintended turn-on of the synchronous-rectifier is possible. |
