自举电路在MOSFET驱动中的应用

Applications of Bootstrap Circuit to MOSFET Drivers

以美国IR公司生产的IR2110集成驱动芯片为例,详细分析了该芯片自举电路在高压驱动中的典型和特殊应用,同时介绍了由IC555组成的自举电路在低压电路驱动中的应用,具有较强的工程实用价值。

This paper introduces the integrated driving circuit IR2110 which is made by IR Co. in USA. Several typical and special applications of its bootstrap circuit for high voltage circuits are analysed. A bootstrap circuit using IC555 is described as well for the low -voltage driving circuit, These circuits are useful in practice .
