Dimmer circuit using SCR - TRIAC - ElecCircuit
The AC light dimmer circuit can control light bulb or speed AC motor, we use a TRIAC and SCR as main, and adjust potentiometer and switch. LEARN more
Triac Circuits & Circuit Design » Electronics Notes
Triac variable power or dimmer circuit. One of the most popular triac circuits varies the phase on the input of the triac to control the power that can be dissipated into load. This is the form of circuit that is widely used in circuits for incandescent light dimmers in domestic applications.
The Triac - How Dimmer Switches Work | HowStuffWorks
In the last section, we saw that a dimmer switch rapidly turns a light circuit on and off to reduce the energy flowing to a light switch. The central element in this switching circuit is a triode alternating current switch, or triac. A triac is a small semiconductor device, similar to a diode or transistor. Like a transistor, a triac is made up of different layers of semiconductor material.

dimmer - How to use SCR to control the power of a heater
I wish to understand how to use SCR in a dimmer with a given heater resistance value and an input voltage frequency value. My goal should be to fully understand how I should pick the other components and if the schematics that I provided below are right or wrong. The first schematic is very simple.
Basic Triac-SCR Projects Circuits Tutorial
A triac is a bidirectional, three-terminal dual, back-to-back Thyristor (SCR) switch. This device can switch the current in either direction by applying a small current of either polarity between the gate and main terminal two. The triac is fabricated by integrating two thyristors in an inverse parallel connection.

An SCR is a four-layer PNPN silicon semiconductor device. It has three external terminals (anode, gate, and cathode) and uses the alternative symbols of Figure 1(a) and has the transistor equivalent circuit of Figure 1(b)re 2 shows the basic way of using the SCR as a DC switch, with the anode positive relative to the cathode, and the SCR controlled via its gate.
