中文摘要: 功率MOSFET是理想的开关,在超声波电发生器、高频开关电源、高频焊机等方面使用广泛,但因驱动线路参数设计欠优而使MOSFET管烧坏的情况时有发生.根据器件和电路参数,推导出开关期间的栅极电压、漏极电流和漏极电压的封闭解.通过比较仿真结果,为功率MOSFET的驱动电路设计提供理论指导.
中文关键词: 解析分析  电路模型  过渡过程
Abstract:The power MOSFET is almost an ideal switch, which is used widely in the ultrasonic electric generator, high frequency switching mode power supply and high frequency welding power supply.The phenomenon that MOSFET is devastated occurs frequently because the design of the drive circuit is not optimized.Closed-form solutions for the gate voltage, drain current, and drain voltage during the switching interval, in terms of each of the relevant device and circuit parameters, are derived.By comparison of the results of emulation, the theoretical direction for designing driver circuit of power MOSFET is provided.
