Sometimes we make electronic circuit designs, and then we see that one single TRIAC cannot take all the big current of a very heavy load. This heavy load can be a huge heater, a big motor, or too many lights. In this condition, we get a simple idea. We think that we can connect two […]

Using Triacs for Controlling Inductive Loads
Here I have tried to investigate a few enhanced triac based phase controller circuits which can be recommended for controlling or operating inductive loads like transformers and AC motors much safely than earlier traditional triac based circuit dimmer circuits. Using Triacs for Controlling AC Loads A Triac is a semiconductor device used for switching AC […]
Triacs – Working and Application Circuits
A triac can be compared to a latching relay. It will instantly switch ON and close as soon as it’s triggered, and will remain closed as long as the supply voltage remains above zero volts or the supply polarity is not changed. If the supply is an AC (alternating current), the triac will open during […]
