TRIAC triggering circuit using DIAC Circuit Analysis YouTube
What is Time-Proportional Phase Control using Triacs or Thyristors? It is a system in which the triac is triggered with calculated lengths of PWM pulses allowing the triac to conduct intermittently for specific lengths of the mains 50/60 Hz frequency, as determined by the PWM pulse positions and time periods.

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.
