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 […]
110 V to 310 V Converter Circuit
The discussed circuit is a solid state AC to DC voltage converter that will convert any AC input between 85 V and 250 V into a constant 310 V DC output. This kind of circuits are normally use in LCD TV sets for operating the system through inputs from 100 V AC to 250 AC. […]
5V, 12V Buck Converter Circuit SMPS 220V
This step down buck converter will convert a 220V AC input from mains supply to 5V or 12V or 24V DC with 90% efficiency. The proposed buck converter is an SMPS circuit using the IC VIPer12A from STMicroelectronics. The circuit uses negligible number of external components yet is able to operate directly from mains AC input. The Buck […]
Make this 220V to 12V SMPS Using UC2842 IC
This UC2842 IC based SMPS design is simple, cheap and efficient kind of isolated power supply. We can use it in off-line stuff like AC-DC adapters, battery chargers and all those small power supplies. What is cool? It takes that high voltage AC then steps it down and then keeps input and output fully isolated […]
The Role of Inductor Coil in SMPS
The most crucial element of a switched mode converter or an SMPS is the inductor. Energy is stored in the form of a magnetic field in the core material of the inductor during the brief ON period (ton) switched through the connected switching element such as MOSFET or a BJT. How the Inductor Works in […]
