Simulation of an Inductive Coupled High Frequency Resonant Gate Driver Circuit

The implementation of an independent-duty-cycled
high frequency resonant gate driver (RGD) circuit utilizing an
inductive coupled linear transformer is proposed and simulated
using PSpice circuit simulator. The totem-poled configuration of
driving MOSFETs that makes the resonant LC network is used
in the proposed RGD circuit. The free-wheeling diodes are used
to recover full energy where most of the charged and discharged
operating current flow in the resonant inductor is returned back
to the input source during switching cycle transition. The work
has been carried out using 1 MHz switching frequency with
fixed input and load conditions. With each pair of driving
MOSFETs providing D and 1-D of switching ratios, the turn-on
and turn-off speed has been improved by 12 % and 23 %
respectively while the total RGD losses reduced to 4 %.
