微网快速开关系统驱动电路的研究

摘要

针对新型微网系统FREEDM（Future Renewable Electric Energy Delivery and Management）中的快速开关系统，提出了一种新型的IGBT驱动控制电路。将IGBT应用于FREEDM的快速开关系统中，根据其在不同故障状态下的不同关断特性，利用集电极退饱和原理，研究设计了具有双故障检测支路的IGBT驱动控制电路，从而保证IGBT在FREEDM中的可靠关断。最终通过Sa-ber仿真和实验验证了驱动控制电路能够在各故障状态下可靠地关断IGBT。%With respect to the fast switching system in the new micro grid system FREEDM (Future Renewable Electric Energy Delivery and Management),this paper proposes a new IGBT drive control circuit.The IGBT is used in the FREEDMfast-switching system.Based on its different switching-on/off characters in different fault conditions,by using collector off-saturation principle,this paper gives a design of an IGBT drive control circuit with double fault detection branches,thus ensuring reliable switching-on/off of the IGBT in the FREEDM.Finally,through Saber simulation and experiment,it is verified that the drive control circuit can reliably switch off the IGBT in different fault conditions.
