摘要晶闸管双向开关作为一种常见的固态开关,可应用于与背靠背变流器并联的场合,如交直流混合输电、风电机组低电压穿越。为了解决此类场合下晶闸管开关的快速关断问题,提出了一种新型的关断策略。根据晶闸管上电流的方向,通过配置变流器中IGBT的开关组合,利用直流母线电压强迫晶闸管快速关断。基于二阶振荡电路的模型,详细推导了关断时间与电路参数的数学关系,深入分析了直流母线电压在关断过程中的下降情况。实验结果表明,该关断策略能够大大缩短晶闸管关断的时间,为背靠背变流器的快速响应创造了条件。

Abstract：As a common solid-state switch, the thyristor bidirectional switch can be used in parallel with the back-to-back converter occasions, such as AC-HVDC hybrid transmission and wind turbine low-voltage-ride-through. A new forced turn-off strategy has been proposed, in order to shut down the thyristor immediately. The strategy makes use of DC bus by assigning switch status for IGBT of the converter, according to the direction of current flows through thyristors. Based on the model of second-order oscillation circuit, mathematical relationship of turn-off time and circuit parameters has been derived, while declination of DC voltage during the turn-off process has also been analyzed. Experiment results proved that the strategy can dramatically shorten the turn-off process of thyristor bidirectional switches, to guarantee fast response of the parallel converters.
