A New Resonant Gate-Drive Circuit With Efficient Energy Recovery and Low Conduction Loss. Eberle, W., Liu, Y., & Sen, P. C. IEEE Transactions on Industrial Electronics, 55(5):2213-2221, May, 2008. doi abstract bibtex In this paper, a new resonant gate-drive circuit is proposed to recover a portion of the power-MOSFET-gate energy that is typically dissipated in high-frequency converters. 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 that is present in other methods. The proposed circuit also achieves quick turn-on and turn-off transition times to reduce switching and conduction losses in power MOSFETs. An analysis, a design procedure, and experimental results are presented for the proposed circuit. Experimental results demonstrate that the proposed driver can recover 51% of the gate energy at 5-V gate-drive voltage.
