Abstract :
This paper describes an active voltage control for IGBT connected in series. The gate drive circuit not only amplifies the control signal, but also control the IGBT´s dv/dt and over voltage during switching transient. This make the switching performance less dependent on IGBT itself. This paper provides a stability analysis to judge the controller stability. The experiment results show the IGBT voltage banlancing under active voltage control.
