triac Firing angle control circuit
Proportional-control triac triggering circuit TDA1023/T FUNCTIONAL DESCRIPTION The TDA1023 generates pulses to trigger a triac. These pulses coincide with the zero excursions of the mains voltage, thus minimizing RF interference and mains supply transients. In order to gate the load on and off, the trigger
SCR TRIGGERING BY UJT, POWER CONTROL CIRCUIT USING DIAC AND TRIAC YouTube
A power controller device which uses a voltage-to-frequency converter in conjunction with a zero crossing detector to linearly and proportionally control AC power being supplied to a load. The output of the voltage-to frequency converter controls the "reset" input of a R-S flip flop, while an "0" crossing detector controls the "set" input.

Proportional-control triac triggering circuit The TDA 1023 generates pulses to trigger a triac. These pulses coincide with the zero excursions of the mains voltage, thus minimizing RF interference and mains supply transients. In order to gate the load on and off, the trigger pulses occur in bursts thus further reducing mains supply pollution.
