Abstract: An improved method of firing angle control of thyristor type converters and particularly cycloconverters each of the component waveforms of the converter as well as the composite output waveform of the converter are summed with a reference waveform and the difference resulting from each of the summations is integrated. The firing angles of the thyristors are established when a predetermined relationship exists between the integral corresponding to the composite output waveform and the integrals corresponding to the component waveforms. A system of control is employed wherein the firing points are determined as a function of the integral of the converter output waveform.

Abstract: A firing circuit for semiconductive controlled rectifiers to be fired in sequence, characterized in that means are provided for storing energy at the gate of a controlled rectifier about to be fired from the drive pulse of the preceding rectifier, the stored energy being discharged into the gate of the rectifier about to be fired upon initiation of its drive pulse to supply momentary peak drive and prevent high local dissipation.

Abstract: Firing circuitry is disclosed for controlled switching devices such as silicon controlled rectifiers wherein a capacitor is charged during the OFF time of the switching device and is discharged into the gate electrode of the switching device at the same time that a conventional firing pulse is applied thereto, thereby providing a composite firing signal having a high initial amplitude which decays to the level of the conventional pulse.
