ABSTRACT:
A driver circuit which is responsive to an input AC voltage for providing a drive signal to a load circuit for each activation of a switch. A triggering signal generated by a trigger circuit in response to the activation of the switch energizes a timing circuit during a negative cycle of the input voltage. A control signal from the timing circuit energizes a firing circuit for a selected time period. The drive signal is applied to the load circuit during the time interval in which the firing circuit is energized by the timing circuit.
