摘要
从载流子的扩散和漂移两个方面分析了晶闸管的开通过程机理,开发设计了结合MOSFET和单片机在内的强触发电路,实现了开通速度快、脉冲宽度和触发电流强度以及触发电流上升率任意可调节等功能。在此基础上,通过实验室搭建晶闸管开通特性试验平台,研究了门极触发电流强度,触发电流前沿上升率(di/dt),触发脉冲宽度,工作电压,以及门极光刻图案等因素对晶闸管开通时间以及开通损耗的影响。试验结果表明:增加门极触发强度和和触发电流上升率、增大工作电压、改善门极光刻版型有利于缩短晶闸管开通时间。另外,试验研究表明,提高触发电流上升速率能有效减少开通过程中的能量损耗。
The switching process of thyristors has been analyzed from the aspects of transmission carrier and carrier density.The effect of high current triggering on switching characteristics of triggered thyristors is investigated.Based on fast switching characteristics and flow capacity,high current trigger circuit has been designed.The relationship of switching characteristics with different triggering current and operation voltages has been studied.The experiment results indicate that the switching time of thyristors is determined by triggering mode and operation voltage.The delay time and breakdown time can be shortened by high current mode and high operation voltage,respectively,which can improve the switching characteristics efficiently.
