Abstract
In the control of power supplied to a load from an a.c. power source by varying the phase angle of the a.c. power alternation at which conduction is initiated, conduction triggering pulses are generated by the use of a single capacitor which is first charged at a selected rate starting from a time corresponding to a predetermined phase angle of the a.c. power alternation, until the voltage thereacross reaches a first value, whereupon a triggering pulse is initiated, and the capacitor is then charged at a selected rate until the voltage thereacross reaches a second value, whereupon the triggering pulse is terminated.
