In this paper, the authors propose a new resonant gate driver circuit for a soft switching synchronous buck converter in a fixed load condition. The switching energy can be fully recovered during current commutation phase in the gate driver while the diode conduction losses in the low and high side switches can be substantially reduced by employing additional L and C resonant in the circuit. Using PSpice simulation, the optimization technique has been studied. From the predetermined pulse width of the generated signals, the optimized resonant inductor current is observed to generate less oscillation and hence lower the switching loss.
