    • This invention relates to semiconductor switching circuitry employing thyristors. More particularly, the invention relates to secondary slave control circuitry for series-connected thyristors capable of controlling high voltage direct current power wherein the thyristors are operated as a plurality of modules of thyristors, each module having a master thyristor which is turned on or off in synchronism with the other master thyristors in the series string. Turn-on of the master thyristor in each module, for example, immediately initiates sequential turn-on of the other thyristors in its associated module such that turn-on of all thyristors in the string is achieved much more rapidly, enabling the number of thyristors in a series string to ge greatly increased.
    • 本发明涉及采用晶闸管的半导体开关电路。 更具体地,本发明涉及用于串联连接晶闸管的辅助从属控制电路,其能够控制高压直流功率,其中晶闸管作为晶闸管的多个模块来操作,每个模块具有在该晶闸管中导通或断开的主晶闸管 与串联串中的其他主晶闸管同步。 例如,每个模块中的主晶闸管的导通,立即启动其相关模块中的其他晶闸管的顺序导通,使得串中的所有晶闸管的导通实现得更快,使晶闸管的数量 在一串系列中大大增加。
