关键字：SiC BJT dual-souree base driver LTspice ringing reversing Current
摘要：As SiC BJT is a current-controlled device, it becomes a trivial issue to achieve both a low power consumption and competitive switching performance. The dual-source base driver is a perfect candidate to achieve these objectives. However, it often exits ringing phenomenon and reversing current phenomenon, which degrades performance. This paper investigates the reasons for above phenomenons. As for ringing, the switching process is established as LCR circuit and suggestions for dual-source driver design are provided. Moreover, this paper discovers the reversing current phenomenon and introduces the new control methods to avoid it. Both ringing and reversing current are validated through LTSPICE simulation and experiment.
