A voltage to frequency converter circuit converts a proportionately varying input voltage int a proportionately varying output frequency. The first design is using the IC VFC32 which is an advanced voltage to frequency converter device from BURR-BROWN specifically designed to produce an extremely proportional frequency response to the fed input voltage for a given voltage […]

Transformerless Voltage Stabilizer Circuit
In this post I have explained a simple circuit design which ensures a perfectly stabilized 220 V or 120 V mains voltage across the connected load, without using relays or transformers, rather by the use of accurately dimensioned and self adjusting PWM pulses. The idea was requested by Mr. Mathew. Warning: Circuits I have explained […]
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 […]
100 amp Variable Voltage Power Supply Circuit Diagram
The post describes a simple but extremely versatile 100 amp, variable voltage power supply circuit using just a few BJTs in parallel and in a common collector mode. The idea was requested by Mr. Andre. Technical Specifications Hello Swagatam, I was wondering if you could possibly assist me. on the blogs I have seen some […]
SG 3525 Automatic PWM Voltage Regulation Circuit
In this post I have explained a simple configuration which can be added with all SG 3525/3524 inverter circuits for implementing automatic PWM output voltage regulation by the IC. The solution was requested by Mr. Felix Anthony. The Circuit Problem: Sir, I would need your help on a project about a schematic that I do […]
