一种基于串联压接型IGBT的主动均压控制方法
摘要：
本发明提供一种基于串联压接型IGBT的主动均压控制方法，所述方法包括：压接型IGBT源漏电压反馈控制；压接型IGBT门极电压反馈控制；压接型IGBT源漏电压变化率反馈控制。本发明提供的基于串联压接型IGBT的主动均压控制方法，通过引入多重闭环反馈，使压接型IGBT开关过程中集射极电压跟随集射极参考电压变化而变化，从而实现压接型IGBT直接串联中开通与关断暂态过程中各串联IGBT阀端电压均衡。
摘要（英）：

The invention provides an active voltage-equalizing control method based on a series compression type IGBT. The method comprises: feedback control of source and drain voltages of a compression type IGBT is realized; feedback control of a gate voltage of the compression type IGBT is carried out; and feedback control of a source-drain voltage changing rate of the compression type IGBT is carried out. According to the method provided by the invention, with introduction of multi-closed-loop feedback, collector and emitter voltages during the compression type IGBT switch process change with changes of reference voltages of the collector and emitter, so that equalizing of all series IGBT valve voltages during the on-off transient process in compression type IGBT direct series connection is realized.
