Latest Patents

Arnold W Feld holds a patent for a Thyristor Control System. This invention involves coupling an induction motor to a three-phase AC source through thyristors that are controlled by a digital control circuit. The system features an adjustable device that gates a selected number of clock pulses to a control counter. As one of the AC phases becomes positive, the control counter is incremented or decremented by clock pulses until it reaches a predetermined count. This triggers a means to generate a trigger pulse, which fires a thyristor. Additionally, the trigger pulse gates clock pulses to a second control counter that counts to 120 degrees and 240 degrees, facilitating the firing of other thyristors. In a speed feedback embodiment, the rotation of the motor generates a feedback signal that is compared with a desired speed signal to adjust the count of an up/down counter, which is then loaded into the control counter.
