摘要：

In this paper, the influence of module internal structure, gap between and substrate, chip layout on multi chips turn on consistency are analyzed, taking the 3300V-1500A IGBT module as example. the copper foil area of the drive PCB should be expanded as much as possible, and the gate copper foil and the emitter copper foil should overlap as much as possible to offset the influence of the power side current change on the drive signal. On the chip layout, the difference between the gate path and the emitter path length should be minimized to improve the consistency of the driving signals of different chips. The gap between the drive PCB and the backing plate should be increased as much as possible to reduce the impact of the power side current change on the drive side.
