Abstract :
An analysis and improvement of the switching behaviour of low voltage power MOSFETs with high current ratings is presented. Different turn-off active gate control circuits are described and their performance is analyzed with the focus on the reduction of the overvoltage at turn-off under the precondition of limited increasing of switching losses. The control methods are experimentally compared to a basic gate drive circuit for two different types of low voltage power MOSFETs.
