Study on Resonant Gate Driver circuits for high frequency applications

Abstract

This paper presents an overview on advantages and limitations of existing resonant gate drivers for the high-frequency applications. Conventional gate drive circuits dissipate energy in gate resistance and this energy is independent of gate resistance. Instead of dissipating all the energy, some of the energy can be recovered or recycled using the principle of resonance. This paper analyzes various gate drive circuits and presents their advantages and limitations. The gate drive circuits are simulated on LTspice Simulation Software. Simulation results are presented to show the effectiveness of the analysis.
