IGBT(Insulated Gate Bipolar Transistor,绝缘栅双极型晶体管)是一种由BJT(双极型三极管)和MOS(绝缘栅型场效应管)组成的复合全控型电压驱动式功率半导体器件。它结合了MOSFET的高输入阻抗和BJT的低导通压降的优点,具有驱动功率小、饱和压降低的特点。 IGBT的 ...
IGBT:IGBT(Insulated Gate Bipolar Transistor),绝缘栅双极型晶体管,是由BJT(双极型三极管)和MOS(绝缘栅型场效应管)组成的复合全控型电压驱动式功率半导体器件, 兼有MOSFET的高输入阻抗和GTR的低导通压降两方面的优点。GTR饱和压降低,载流密度大,但驱动电流较大 ...
还有默认这两个信号已经经过了死区控制,不回产生同时导通的问题。 除了第一个图外,功率管上必须并联续流二极管,要么是MOS管里自带的,要么就是BJT再并联的,或者MOS管并联肖特基。 其实我们大家平时控制电机用的都是如图1所示的那种样子, 这种模式叫 ...
