In this post we will unravel a few homemade crude 220V to 110V converter circuits options which will enable to user the user use it for operating small gadgets with a different voltage specs. UPDATE: An SMPS circuit is the recommended option for building this converter, so for an SMPS 220V to 110V converter design […]

110V, 14V, 5V SMPS Circuit – Detailed Diagrams with Illustrations
In this post I have explained how to apply the IC L6565 for making a compact multi purpose 110V, 14V, 5V SMPS circuit using minimum number of external components. Implementing quasi-resonant ZVS flyback The IC L6565 from ST Microelectronics is designed as a current-mode primary controller chip, to specifically suit quasi-resonant ZVS flyback converter applications. The […]
How to Repair a Switch-Mode-Power-Supply (SMPS)
In this post we try to diagnose a burnt SMPS circuit and try to troubleshoot and repair the circuit. The shown unit is a cheap readymade Chinese make SMPS circuit. This article is written as per the request made by Mr. Kesava. My SMPS got Burnt The below attachment is 12v 1.3 amps SMPS for […]
2 Compact 12V 2 Amp SMPS Circuit for LED Driver
In this post I will comprehensively discuss a 2 simple 12V 2 amp SMPS circuit using the IC UC2842. We study a 2 amp flyback design by evaluating various formulas, which provides the exact selection details for the transformer winding and the parts specifications. Design#1: Introduction The first design is based on the versatile IC VIPer53-E. […]
LM317 Variable Switch Mode Power Supply (SMPS)
So far in this website we have studied LM317 based linear power supply circuits, here I have explained how an LM317 can be executed as a variable switch mode power or SMPS with zero loss. LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage […]
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 […]
