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 […]

SMPS DC CDI Circuit for Motorcycles using Ferrite Core Transformer
The circuit presented here is for a DC-CDI which are used in motorcycles. A DC-CDI is the one in which the high voltage (200-400VDC) is converted from 12V supply voltage. Researched and Submitted by: Abu-Hafss Studying the circuit, we see that it has two parts i.e. the smps CDI unit, enclosed in the pink box […]
Guitar Jammer Circuit (Mix an External Audio with your Guitar)
This Guitar Jammer circuit I have explained below enables you to jam out to your favorite songs from your cellphone or computer. You can mix an external audio track with your guitar sound, then use headphones to listen to the blended result. Imagine playing note-for-note copies of legendary guitarist’s riffs and exchanging scorching pentatonics, “hammer-ons,” […]
Transformerless LED Bulb Circuits using Capacitors
In this post I have elaborately explained how to build simple transformerless LED bulb circuits using many LEDs in series and powering them through current controlled capacitive power supply circuit. Safety Note: These circuits operate directly from mains AC voltage without galvanic isolation, meaning live components carry high voltage when energized. Standard electrical safety practices […]
3 Best Transformerless Inverter Circuits
As the name suggests, an inverter circuit that converts a DC input into AC without depending on an inductor or a transformer is called a transformerless inverter. Since an inductor based transformer is not employed, the input DC is normally equal to the peak value of the AC generated at the output of the inverter. […]
How Shunt Regulator TL431 Works, Datasheet, Application
In this post I have explained how a shunt regulator IC works typically in SMPS circuits. We take the example of the popular TL431 device and try to understand its use in electronic circuits through a few of its application notes. Electrical Specifications Technically the device TL431 is called a programmable shunt regulator, in simple […]
