摘　　要：针对IGBT模块由于电流超出安全工作区而损坏的问题,设计了一种基于HCPL-316J驱动芯片的低成本高可靠性IGBT驱动电路,详细分析了过流保护时驱动电路的工作过程,之后通过Pspice软件建立了驱动电路的仿真模型,最后通过实验验证了驱动电路过流保护理论分析和仿真模型的正确性。The IGBT module will be damaged when the current is beyond the limit of safe operation area. This paper designed a low cost and high reliability driving circuit based on the HCPL-316J driving chip. The detailed driving circuit and working process were analyzed considering the over-current protection feature first. Then the simulation circuit of the drive circuit was established using the simulation software. The simulation result verified the theoreti- cal analysis. Finally the experimental results also verified the validity of the analysis of the IGBT drive circuit.
