| Abstract |
This paper shows a new insulated gate driver with efficient energy recovery for the top and bottom switches of an half bridge. This gate driver is design to drive the main switches of a 3MHz resonant converter (48V/3.3V 20Watts). The originality of this driver comes from its low number of devices and its high frequency operation even if it drives switches having a high gate capacitor, as TrenchMos. The gate driver theoretically only provides the power dissipated by the internal power mosfet gate resistance. This gate driver is dedicated to high frequency resonant converter with a 0.5 duty cycle. |
