摘要

本文介绍了标准大功率GTO (csg3003 -45)在硬盘驱动条件下的通断瞬态动态特性。在Spice和abb双鱼座(2D器件和电路模拟器)中对大功率开关器件及其栅极单元进行了建模和仿真，并对其性能进行了预测。实现了能够处理高达|dI/sub G//dt|=5 kA//spl mu/s的栅极单元，并且在测量过程中观察到器件原始规格(根据生产商提供的数据表)的巨大改进。在导通和关断瞬态过程中，模拟结果与实验室结果非常吻合。这是一个很好的指示，所有2000个并行细胞的分割GTO的同质操作。

Hard drive of high power GTOs: better switching capability obtained through improved gate-units

The paper presents the dynamic behavior of a standard high power GTO (CSG 3003-45) during turn-on and off switching transients under hard drive conditions. The high power switching device and its gate-unit were modeled and simulated in Spice and ABBPisces (2D device and circuit simulator) and their performances were predicted. A gate-unit capable to handle up to |dI/sub G//dt|=5 kA//spl mu/s was realized and tremendous betterment of device original specifications (as per data-sheet supplied from the producer) were observed during measurements. Very good agreement between simulation and laboratory findings were notified during turn-on and turn-off transients. This is a good indication of homogeneous operation of all 2000 parallel cells of the segmented GTO.
