一种改进型MOSFET隔离驱动电路研究
资料介绍
分析传统MOSFET变压器隔离驱动电路存在的缺点,介绍了一种改进型驱动电路。在驱动脉宽较窄（占空比较小）的情况下,改进型驱动电路能维持必要的栅极负偏压,确保MOSFET快速可靠关断,减小关断损耗。该电路也适用于IGBT开关器件,可广泛用于各类开关电源,包括交直流变换器、变频器、不间断电源等领域。
The text analyzes disadvantages of traditional MOSFET isolated driving circuit,and introduces an improved circuit.This circuit can hold sufficent negative gate voltage to make sure MOSFET cut off rapidly and reliably in case of less duty. The circuit is also suitable for IGBT,and is used for many kands of switching power,including AC/DC or DC/DC converter,frequency converter and UPS.
