Power Supply Circuits

The post provides interesting information regarding the making of a 1.5V to 12V converter circuit using a couple of transistors and an inexpensive coil. The idea was requested by Mr. Keith. The Circuit Request I found your blog and have searched for an answer to my question but I’m just not finding it…. What I want to do […]

We all have heard a lot about buck and boost circuits and know that basically these circuits are used in SMPS designs for stepping up or stepping down a given voltage at the input. The interesting thing about this technology is that it allows the above functions with negligible heat generation which results in a […]

In this article I have explained a simple variable regulated voltage power supply circuit which utilizes just a single transistor. The design can be very handy for the new electronic hobbyist Main Features The explained power supply includes an adjustable voltage feature which is an essential feature for every electronic enthusiast. However making one such […]

This simple MOSFET controlled transformerless power supply circuit can be used for delivering a continuously variable 0 to 300V DC output and a current control from 100 mA to 1 Amp. To protect against my high voltage research projects from going up in smoke permanently, I developed an easy circuit which is able to render […]

In the following post I have explained a linear voltage regulator power supply circuit using the IC LM196 which is capable of handling up to 10 amps of current and is able to provide a variable voltage right from 1.25V to 15V DC. About the IC LM196 or LM396 The IC LM 196 is single […]

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 Referring to the circuit diagram below, we see that the entire idea is based upon the versatile, evergreen IC 555. […]
