A flyback configuration is the preferred topology in SMPS application designs mainly because it guarantees complete isolation of the output DC from the input mains AC. Other features include low manufacturing cost, simpler design and uncomplicated implementation. The low current DCM version of flyback converters which include output specification lower than 50 watt are more […]
Power electronics was developed to ensure higher efficiency in converter designs in terms of cost, weight and consumption.
Thus we can see why SMPS based systems are compacts and lighter in weight than the conventional iron cored converters, and these are additionally very energy efficient since SMPS circuits waste very little power while operating.
However handling power factor correction becomes a major issue while designing power electronic circuits, and in this segment we also have a detailed article regarding the correct implementing of PFC in SMPS circuits.
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 […]
In this project we are going to step down 12v D.C to any D.C value between 2 and 11volts. The circuit which steps down the D.C voltage is known as buck converter. The output voltage or step down voltage needed is controlled using a potentiometer connected to arduino. By Ankit Negi INTRODUCTION TO CONVERTERS: There […]
In this post we learn 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 quasi-resonant […]
