How to Connect 5V Relay Module: Testing and Interfacing
In this post we are talking about this handy little gadget called a 5V single-channel relay module. It is super useful for our microcontroller projects whether we are using Arduino, Raspberry Pi, or even the ESP8266/ESP32. Let us break it down together, what it is, how it works, and how we can connect it. Understanding […]
Difference Between Forward Converter and Flyback Converter
We know SMPS can be made in different ways, but two common ones are flyback converter and forward converter, which may look same at first. But inside working is not same at all, so this part matters before you design transformer or power stage. Flyback Converter We see a flyback converter works in a way […]
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 […]
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 […]
High Voltage, High Current Buck Converter Circuit using Isolated Gate Driver
This is a high voltage 310V to 60V buck converter, so we have that big 310V DC coming in which we usually get after rectifying 220V AC mains. So now that high DC is there and we want to push it down to something like 60V or lower for battery charging or similar work. Audio/Video […]
