    • A motor control apparatus to supply current from a D-C source to an electric motor has a thyristor chopper circuit, the duty factor of which is controlled depending on a current instruction signal. The thyristor chopper circuit is provided between the terminals of the D-C source in series with an electric motor, and has main and auxiliary thyristors. A series connection of a capacitor and a reactor, forming commutating elements, is connected across the auxiliary thyristor and oscillates to generate a pulse of current through a forward diode in order to turn off the main thyristor when the auxiliary thyristor is turned on. In addition, a saturable current transformer is so provided that through a primary winding thereof chopper current flows, and the secondary winding operates as the reactance of the commutating elements. Current flowing through the secondary winding therefore depends on the chopper current flowing through the primary winding.
    • 从D-C源向电动机供给电流的电动机控制装置具有晶闸管斩波电路,其占空因数根据电流指令信号而被控制。 晶闸管斩波电路设置在与电动机串联的D-C源的端子之间,并具有主晶闸管和辅助晶闸管。 电容器和电抗器的串联连接,形成换向元件,跨过辅助晶闸管连接并振荡,以产生通过正向二极管的电流脉冲,以便在辅助晶闸管导通时关断主晶闸管。 此外,可饱和电流互感器被设置为通过其初级绕组斩波电流流动,次级绕组作为换向元件的电抗工作。 因此,流过次级绕组的电流取决于流过初级绕组的斩波电流。

    • A protective circuit for protecting a main d.c. circuit of the kind comprising a d.c. power source, a d.c. load, a contactor and a chopper. In the protective circuit, a resistor is connected in parallel with the series-connected contactor and load to permit continuous application of power supply voltage across the chopper. A circuit is connected to the connection point of the load and chopper to provide a signal synchronous with on-off of the chopper, and the output signal of this circuit and a signal corresponding to a chopper-on signal are applied to a logic circuit which provides the logical sum of these inputs for the detection of commutation failure of the chopper. The output of the logic circuit turns on a thyristor for deenergizing the contactor thereby disconnecting the load from the power source.
