摘要
本文首先谈论了IGBT的驱动电路的基本要求和过流保护分析,然后运用IGBT集电极退饱和原理,提供了一个采用分立元件构成的IGBT驱动电路和过流保护电路。仿真和试验结果证明了所设计驱动电路的可行性。
This paper discussed the IGBT drive circuit and the basic requirements of over-current protection, and then use IGBT col- lector retreat saturation principle, provide a use of discrete components constitute the IGBT driver circuits and over-current protection circuit. Simulation and test results proved that the design of the feasibility of driving circuit.
