摘    要:可关断晶闸管(GTO)要求其驱动电路提供的驱动电流的前沿应有足够的幅值和陡度,且一般需要在整个导通期间施加正门极电流,关断需施加负门极电流,幅值和陡度要求更高.主要结合GTO门极驱动的要求,提出一种新型的直接门极驱动电路,这种新型门极驱动电路结构简单,电感值低,因此可以为GTO提供快速的门极脉冲.每个GTO门板驱动完全独立,一定数量的GTO就可以串联使用来适应高压需要.

关 键 词:直接门极驱动  晶闸管

Abstract:GTO is conventionally driven on a high enough amplitude and steepness with its current leading edge of drive circuit,which applies positive gate current for openness and negative current for shutoff.A new circuit for direct gate drive in respect of the requirements for GTO gate drive was advanced.This new drive circuit features compact structure and low inductance,which can give rapid gate pulsation for every GTO gate independently,and consequently,high-voltage power can be imposed on certain GTOs connected...
