| 摘 要： | 高频开关电源都会有较大的驱动损耗,本文提出谐振驱动技术,它可以在冲放电过程中进行有效的能量恢复。在对门极驱动损耗进行简单的介绍以后,本文提出了一个新的电路,该电路有着低驱动损耗、开关速度快、驱动电压箝位和防止误导通等功能,而且它没有占空比限制。

| Abstract: | High frequency pulse-width modulation (PWM) converters generally suffer from excessive gate drive loss. This paper presents a resonant gate drive circuit that features efficient energy recovery at both charging and discharging transitions. Following a brief introduction of metal oxide semiconductor field effect transistor (MOSFET) gate drive loss,a new resonant MOSFET gate drive circuit is then presented. The new circuit produces low gate drive loss, fast switching speed, clamped gate voltages,immunity to false trigger and has no limitation on the duty cycle. Experimental results further verifyits functionality. |
