    • Electrical switching device for controlling current now from an alternating current source (10) and having a main thyristor (14, 16) such as a triac or a silicon controlled rectifier connected in series with a load (12) across the source. The control terminal (14c, 16c) of the thyristor (14, 16) is coupled via a diac (30) to a control signal generating circuit (18) operable to vary the conduction interval of the thyristor (14, 16) on each cycle of voltage from the supply (10) by switching the diac (30). A further thyristor (38, 42) such as a triac or silicon controlled rectifier is connected to be responsive to the switching of the diac (30) to be itself switched so as to provide a current now path from the control terminal (14c, 16c) of the main thyristor to render the main thyristor insensitive to immediate further control under influence of the diac.
    • 电开关装置,用于从交流电源(10)控制电流,并具有与跨越源极的负载(12)串联连接的三端双向可控硅整流器或可控硅整流器的主晶闸管(14,16)。 晶闸管(14,16)的控制端子(14c,16c)通过二极管(30)耦合到控制信号发生电路(18),可操作以在每个周期上改变晶闸管(14,16)的导通间隔 的电压(10)通过切换二极管(30)。 另外一个可控硅(38,42)如三端双向可控硅或可控硅整流器被连接以响应于双相变压器(30)的开关自身被切换,从而提供来自控制端子(14c,16c)的电流 ),使主晶闸管对diac影响下的即时进一步控制不敏感。

    • A device for the control of rectifiers which are interconnected in series into four sections (1, 2, 3, 4) comprises a first group (6) of current transformers (7, 8, 9), the first winding (10) of one of which is connected to the output of a generator (11) of controlling current pulses, and further comprises a second group (12) of current transformers (13), the number of which corresponds to that of the rectifiers (5) and which are interconnected, correspondingly to the sections (1, 2, 3, 4) of the rectifiers (5), into sections (14, 15, 16, 17) consisting each of an equal number of current transformers (13), the primary windings (18) of which are inter-connected in series into cascades, whereas their secondary windings (19) are electrically connected to the controlling inputs (22) of the rectifiers (5). The outputs of the secondary winding (25) of the current transformer (7) are connected in series to the the primary windings (10) of the other two transformers (8, 9) of the first group (6) and to primary windings (18) of the middle sections (15, 16) of the current transformers (13) of the second group (12). The outputs of the secondary windings (25) of the two current transformers (8, 9) of the first group (6) are connected to the outputs of the primary windings (18) of the cascade of the outer sections (14, 17) of the current tranformers (13) of the second group (12). The device further comprises two resistors (28, 29), connected in series, the common output (30) of which is connected to the common output (31) of the two middle sections (2, 3) of the rectifiers (5), whereas the other outputs are connected to the outputs of the secondary winding (25) of the current transformer (7) of the first group (6). In parallel to each outer section (1, 4) of the rectifiers (5) are connected capacitors (33, 34).
