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 […]
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 […]
12 V to 30 V High Current Boost Converter Circuit [Variable]
In this post I have explained how to make a high current boost converter circuit which will step up a 12 V DC to any higher level up to 30 V maximum, and at an impressive 3 amp current rate. This high current output can be further enhanced by suitably upgrading the inductor wire gauge […]
