| 摘 要： | IGBT有源电压控制技术（ActiVe Voltage Control,简称AVC）,是在IGBT控制过程中引入多重闭环反馈,使IGBT开通和关断过程中集电极-发射极电压VCE的轨迹始终跟随预先设定的参考信号,实现高压应用时IGBT器件直接串联的同步工作和有效均压。本文介绍了有源电压控制技术的基本概念,串联IGBT的实验波形和相应的损耗计算。

| Abstract: | The so-called IGBT AVC technology is something that during the IGBT control process, various layers of closed loop reaction is introduced to ensure that the pathway of collector-emitter voltage VCE during the process of on-off of the IGBT follows the predefined referential signal, to realize synchronous function and effective voltage-sharing when IGBT components are connected in series with the high-voltage application. The article introduces basic concepts of AVC, experimental wave of IGBT connected in series and related loss calculation. |
