摘要

提出了一种实际损耗可忽略不计的低阻抗隔离式或非隔离式电容驱动器。电容峰值电压完全可预测，驱动器可以自我调节驱动1 nF-10 μ F电容，上升时间不变。电路结果显示，MOSFET栅极驱动损耗低于经典驱动电路功率损耗的2%。

A novel lossless resonant MOSFET driver

A low-impedance isolated or nonisolated capacitor driver with negligible practical losses is presented. Peak capacitor voltages are totally predictable, and the driver can self-regulate to drive a 1 nF-10 mu F capacitor with unchanged risetime. Circuit results exhibit MOSFET gate-drive losses below 2% of the power lost in classical drive circuits.<>
