7 Easy Voltage Doubler Circuits Discussed
In this article I have explained 7 easy to build DC to DC voltage doubler circuits using a single IC 4049 and IC 555 along with a few other passive components. If you are wondering how a simple IC 555 can be used for making a powerful voltage doubler circuit, then this article will help […]
SMPS Voltage Stabilizer Circuit
In this article I have explained a solid state switch-mode mains voltage stabilizer circuit without relays, using a ferrite core boost converter and a couple of half-bridge mosfet driver circuits. The idea was requested by Mr. McAnthony Bernard. Technical Specifications Of late i started looking at voltage stabilizers use in house hold to regulate utility […]
How to Modify SMPS for Adjustable Current and Voltage Output
This article discusses a method through which any ready made SMPS can be converted into a variable current smps circuit using a few external jumper links. In one of the previous articles I have explained how to make a variable voltage SMPS circuit by employing a simple shunt regulators stage, in the present hack also […]
SG 3525 Automatic PWM Voltage Regulation Circuit
