基于光耦ACPL-339J的IGBT驱动电路设计
资料介绍
针对大功率IGBT对驱动和保护电路的要求，采用ACPL-339J智能IGBT门驱动光电耦合芯片设计了大功率IGBT的驱动电路，包括驱动信号整形电路、去饱和（DESAT）电路、门极驱动保护电路等。并且使用改进Push—Pull拓扑结构设计了高效简单的DC／DC隔离电源电路，计算了隔离变压器的设计参数。最后，通过双脉冲和短路实验验证了驱动电路的快速响应能力、安全性、稳定性。
Aimed at the drive and protection circuit requirement of high power IGBT, this paper employed the AC- PL -339J intelligent IGBT gate driver optocoupler chip to design the high power IGBT driver circuit, including the drive signal shaping circuit, DESAT circuit, the gate driver protection circuit, and so on. And it also designed the simple and efficient DC/DC isolation power supply circuit, and calculated the design parameters of the isolation transformer by adopting the improved Push - Pull topology structure. Finally, double pulse and short circuit experi- ment verified the fast response ability, security and stability of the drive circuit.
