In this article we will try to understand how to build a 220V AC to 48 V DC SMPS circuit for charging all types of 48V batteries, using the nice little IC IR2153. However, since 48V battery will require a 56V DC, so we will rather discuss a 220V to 56 V DC battery charger […]

32V, 3 Amp LED Driver SMPS Circuit
In this article I have explained a 32V, 3 amp SMPS circuit which may be specifically used as an SMPS 100 watt LED driver, rated with the same specs. The circuit of the proposed 32 V, 3 amp smps led driver may be understood with the the help of the following points: Circuit Operation The […]
How to Design Customized 220V SMPS Circuits
We many times think that how we can make a SMPS circuit, and we feel that this is very complex. But that is not so because we can do this by following simple manual calculations step by step. We only need to know that SMPS design is always starting from the transformer. We cannot make […]
Convert SMPS into a Solar Charger
In this post I have explained how to convert smps into a solar charger circuit. The method will result in an extremely efficient and fast solar charging of the connected battery. SMPS Solar Chargers SMPSs have become very common nowadays and we find them being used in the form of AC to DC adapters wherever […]
SMPS Flyback Boost Converter Calculator
This calculator tool supports a Boost Converter Flyback setup which means now the code considers: Corrected turns ratio and primary voltage logic since the flyback works by storing energy during “ON” time and transferring to secondary during “OFF” time. Flyback boost topology where output voltage is higher than input. An accurate duty cycle formula for […]
220V SMPS Cell Phone Charger Circuit
In this post I have explained how to make a simple, cheap yet extremely reliable smps based 220V/120V mains operated cell phone charger circuit. Why TNYxxx Tiny Switch is Used The TNY series of tiny switch ICs provide us with an option of making perhaps the smallest possible smps circuits with high reliability. The tiny […]
