In our household, most of the appliances are powered from the AC supply such as Lights, TVs, and Fans, etc. We can turn ON/OFF them digitally if needed, using Arduino and Relays by building a Home ...

For DC it is much easier to control power using PWM where we use mosfets and can close or open it anytime. Howerver, for AC we have to deal with triacs. Triac also, has a gate to control it, but if ...

In this video author will present the most important facts about a controllable diode, the thyristor. He will also build a small experimental circuit to control AC voltage with the help of a triac.

This universal triac controller circuit with optocoupler solves the problem that triacs have when functioning at low temperatures (triac needs higher gate current) by adding a transistor at the output ...
