IGBT管的开关频率能否达到10MHz?如果能达到该用什么驱动芯片驱动呢?求大牛指点!!~?

https://www.zhihu.com/question/41472936/answer/2827098682#comment-10409585929?notificationId=1595795...

1.gate电容?

2.igbt和mos都有结电容,作为压控型器件,需要把这个结电容充电到一定电压才能使器件导通,这个充电的速度取决于驱动器的电流输出能力和结电容那一支路上的阻抗。开关频率快时在dc-dc中可以使用更小的电感和电容达到相同的效果,在开关电源中也可以使用体积更小的变压器,这就是为啥频率高的gan能做出更小体积的充电器

3.意思是…LC那种的吗?
