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.
