A new resonant gate drive circuit with efficient energy recovery and low conduction loss

In this paper, a new resonant gate drive circuit is proposed. The proposed circuit consists of four control switches and a small resonant inductance. The current through the resonant inductance is discontinuous in order to minimize circulating current conduction loss present in other methods. The proposed circuit also achieves quick turn-on and turn-off transition times to reduce switching loss and conduction loss in power MOSFETS. An analysis, design procedure and simulation results are presented for the proposed circuit
