Normally, for standard 220V AC household projects, a single 600V or 800V TRIAC is more than enough. But what if you are working with a very high voltage line, like 1000V AC? A single common TRIAC will immediately burn and short circuit because it cannot handle that much voltage stress. To solve this, we can […]

How to Connect Triacs in Parallel for High Current Loads: Circuit Diagram
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 […]
Switching Two Alternate Loads ON/OFF with IC 555
In this post I have explained how to make a simple IC 555 based alternate relay timer circuit for toggling a couple of loads alternately with a specified length of delay, as determined by the calculated values of the relevant components. The idea was requested by Mr. Sanjoy. Circuit Objectives and Requirements The Design Referring […]
