摘要

作者介绍了在级联码配置下操作的高频，大功率GTO(门关)开关的工作。与传统的门控GTO开关相比，这种配置具有相当大的优势。这包括大大减少关断时间和无漏电操作，因此，能够在更高的开关频率下工作。开关频率的主要限制是尾部损耗;对这一现象进行了详细的研究。

Switching behaviour of GTO cascode switches

The author presents work on a high-frequency, high-power GTO (gate-turn-off) switch operated in the cascode configuration. This configuration is shown to have considerable advantages over conventionally gated GTO switches. These include much reduced turn-off times and snubberless operation, and hence, the ability to operate at increased switching frequency. The major limit on switching frequency is shown to be tail losses; this phenomenon is studied in some detail.<>
