Abstract: 1,008,614. Rectifying; control of D.C. motors. BROOKHIRST IGRANIC Ltd. April 23, 1964 [June 4, 1963], No. 16866/64. Headings H2F and H2J. [Also in Division H3] A control system for a load such as a D.C. shunt motor A comprises a rectifier 2 supplying pulsating D.C. from an A.C. source to a thyristor SCR supplying the load, a firing circuit to fire the rectifier during each pulse and means in series with the rectifier to provide a bias voltage which is applied to the trigger electrode to ensure termination of conduction when the applied voltage falls to a low value. The hold-on current of a thyristor is increased by a negative bias on the trigger, so with the arrangement of the invention the controlled rectifier turns off more reliably than it would without the bias. The firing pulses for the controlled rectifier are applied between the trigger and the end of a low resistance 10 in series with the cathode, the arrangement being such that when there is no firing pulse, but load current is flowing, the voltage across the resistor 10 provides the required bias. A free wheeling diode 12 shunts the load and the resistor 10. The firing control circuit may be a magnetic amplifier, a uni-junction transistor circuit or a valve circuit which is energized from the A.C. supply and provides steep fronted pulses through transformers 26 and 28 in alternate half-cycles of the supply. Load current may be stabilized by a compensating circuit 14 which observes the voltage across the resistor 10 and adjusts the phase of the firing pulses accordingly.
