新型功率MOSFET驱动电路的设计

Design of a Novel Drive Circuit for Power MOSFET’s

提出了一种全新思路的功率ＭＯＳＦＥＴ驱动电路。该电路采用数字电路结构，分立器件少，易实现模块化，波形控制十分灵活，工作频率很高，适用于高频软开关的开关电源及ＤＣ／ＤＣ变换器。

A novel drive circuit has been proposed for power MOSFET’s.Using digital architechture,the new circuit has fewer discrete components,so that it can be easily materialized into a module.Having high operating frequency,the circuit developed is very useful in switching power supply based on high frequency soft switches and DC/DC converters.
