So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]
Newly Updated Circuit Projects:
AC Motor Speed Controller Circuits using Back EMF
In this post I have explained a few circuit diagrams for building AC motor speed controller circuits using back EMF concept. Working Principle of AC Motors So now, all those home type appliances like electric drill machines, sander machines, sewing machines, food mixer machines, etc. they all are mostly using that AC motor which is […]
Do We Need a Freewheeling Diode Across the Inductor in Boost Converter?
So here we are trying to understand whether we must put a freewheeling diode directly across the inductor in a boost converter or not, to safeguard the switching transistor? How Boost Converter Works So in a boost converter, we got one inductor, one power switch like a MOSFET, one diode and one output capacitor. Input […]
SG 3525 Automatic PWM Voltage Regulation Circuit
In this post I have explained a simple configuration which can be added with all SG 3525/3524 inverter circuits for implementing automatic PWM output voltage regulation by the IC. The solution was requested by Mr. Felix Anthony. The Circuit Problem: Sir, I would need your help on a project about a schematic that I do […]
USB 5V To 24V DC to DC Boost Power Regulator Module
This is a USB 5V to 24V Adjustable Boost Converter Module and it helps us step up a lower voltage into a higher voltage which we can adjust as needed. Now let us go through everything in detail step by step. Inputs – Where We Give Power Now we got three ways to power this […]
DC-DC Boost Module (0.9V~5V) to 5V 600mA USB Step-up Board
So this is a DC-DC boost converter that takes a low voltage (0.9V to 5V) and steps it up to a stable 5V. We use this when we have a small battery, but we need 5V output, like for USB devices. It is super useful for battery-powered projects and small electronics. Main Features How It […]
