| Abstract: | By analyzing the transfer function of VCE detection circuit,the electrical parameters of the circuit are reasonably configured.According to the characteristics of IGBT short circuited,a high power IGBT driver protection strategy is proposed based on multi threshold over current protection and variable resistance soft shutdown.This control strategy achieves effective control of the drive to IGBT,and effectively reduces the voltage spikes through switching process due to the di/dt.Finally,the simulation model of IGBT is built in Sabor,and the short circuit protection experiments are completed based on the platform of FZ1500R33HE3.Simulation and experimental results show the feasibility of the driving circuit. |
