In this article we are going to understand in detail how we can create air gap in a ferrite core based transformer which we are using in smps circuits like flyback or boost or forward type. Introduction We must understand that ferrite cores have very high permeability and they saturate very fast if we do […]

How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
Build Customized 220V Flyback SMPS Circuits: 12V, 5A, 60W Example Discussed
In this post I will explain you all the simple formulas, step by step, which you can use for designing and building professional grade 220V AC SMPS flyback converter circuits. As we know the SMPS transformer is the heart of an SMPS design, so here we will learn all the steps, one by step, using […]
Make this DIY Spot Welding Machine using MOT and IC 555
Building a spot welding machine at home, it does not really need those complex SMPS circuits or costly stuff, nope. Instead a much simpler way is there, which people use, and it works quite well. We can use a microwave oven transformer, that MOT, and then add a small timing circuit with it, so now […]
SMPS Spot Welding Circuit using IC SG3525 Explained
Spot welding needs very low voltage but very high current, that too for very short time, so now this whole thing is built around that idea. In this design we push big current in small time period for safely creating the required welding joint, done. Audio/Video Representation How the Circuit Works Now the circuit, it […]
12V, 5 Amp SMPS Battery Charger Circuit
In this article we study a simple flyback based converter design which is implemented as an SMPS 12V, 5amp battery charger power supply, without using a iron core transformer. How it Works The proposed 12V, 5 amp smps battery charger circuit employs a flyback converter topology which results in the required smps based high current, […]
