Electronic 12V DC Capacitive Discharge Ignition (CDI) Circuits

Last Updated on May 16, 2026 by Swagatam 304 Comments

enhanced CDI

In the following post I have explained a simple yet enhanced 12V capacitive discharge ignition system which derives its operating voltage from the battery instead of the alternator for generating the igniting sparks. Since it works independently from the alternator voltage, without depending on a pickup coil signal, it is able to function more efficiently […]

High Voltage, High Current DC Regulator Circuit

Last Updated on May 16, 2026 by Swagatam 69 Comments

high voltage DC stabilizr circuit

We all are pretty familiar with the 78XX voltage regulator ICs or the adjustable types such as LM317, LM338 etc. Though these regulators are outstanding with their specified functioning and reliability, these regulators have one big disadvantage…. they won’t control anything above 35V. Circuit Operation The circuit presented in the following article introduces a DC […]

XL6009 DC-DC Converter IC: Pinout, Working, Circuit Diagram, and Applications

Last Updated on April 15, 2026 by Swagatam Leave a Comment

XL6009 is a DC-DC switching regulator IC, and we use it where lower voltage DC has to be lifted higher, or sometimes changed other ways, boost, buck-boost, flyback, even inverting, all that is possible depending how outside parts are connected. Why XL6009 is More Efficient Than Linear Regulators It is not like old regulator types […]

220V AC to 12V DC Flyback SMPS Circuit using IC 555 (7555)

Last Updated on April 15, 2026 by Swagatam Leave a Comment

This practical flyback SMPS circuit uses ICM7555 as the main oscillator, and yep the whole idea is to take 220V AC mains directly then convert it into isolated low voltage DC through a ferrite transformer.. Unlike many PWM controller designs, here we have very few parts but still it gives mains isolation, voltage feedback, current […]

12V DC to 220V DC Boost Converter Circuit

Last Updated on March 17, 2026 by Swagatam 126 Comments

In this article I have explained a very simple method of acquiring 220V DC from a 12V DC source. The idea utilizes inductor/oscillator based boost topology with the help of the IC 555. Circuit Operation Now let us learn more about this simple 12V to 220V DC boost converter circuit, which is built around IC […]
