Heat Control: The Above circuit shows the typical structure of the DIAC-TRIAC combination used for smooth control of AC power to a Heater. We have used basic components to complete this task. The moc3021 has actually total of 6 pins but pin number 3 and pin number 5 are not used. In this project, we are going to make a TRIAC dimmer circuit for AC Appliances. Figure 3. I have many circuits (ZCS resonant buck converters, VAR control using Thyristor Controlled Inductor etc) to design and simulate that have TRIACs and SCRs in them and I need to fire each of them using different firing angles. When the power supply charges C, the TRIAC dimmer can be delayed to start until the voltage of C rises to the trigger point voltage of DIAC (usually 32 V). Typical component values are 0.1 μF and ≥100 Ω. This circuit works great as a household light dimmer.All parts could be fitted at the rear of a wall switch board and in case the load happens to be below 200 watts, the Triac could work without depending on a heatsink. There isn’t a lot to be explained about the details of the circuit. The below circuit shows the basic TRIAC triggering circuit using DIAC. Figure 4 is a schematic diagram of a typical TRIAC dimmer circuit. TRIAC is a semiconductor device belonging to the family of thyristors. This circuit is an example of a simple lamp dimmer.
