    Abstract: A light-emitting diode is connected through a capacitor to a d-c power supply from which the capacitor accumulates a charge. A thyristor is connected in parallel with the capacitor and the light-emitting diode, and when a control signal is applied to its gate the thyristor turns on and discharges the capacitor through the light-emitting diode which emits a light signal. A commutating circuit responsive to turn on of the thyristor turns off the thyristor after a predetermined time interval.

    Abstract: A high-voltage electric power converter comprises a plurality of electric valves interconnected in a bridge configuration. In operation the valves are cyclically fired in a predetermined normal sequence by a series of relatively short gate pulses respectively applied thereto. For successful starting, the controls are arranged (1) to idle until the concurrence of a starting command and a proper instant of time for firing any one of said valves, and then (2) to apply simultaneously a gate pulse to that one valve and a gate pulse to the immediately preceding valve in said normal sequence. The controls are preconditioned so that the initial firing angle is within certain limits that ensure continuous conduction by the preceding valve at least from the starting instant to the time at which the succeeding valve is fired.
