In this post I have explained about MOSFET bidirectional power switches, which can be used for operating a load across two points bidirectionally. This is simply done by connecting two N-channel, or P-channel MOSFETs back to back in series with the specified voltage line. What is a Bidirectional Switch A bidirectional power switch (BPS) is […]

Solving Inverter “No Load Auto-Shutdown” Problem
In this post I have explained how to trick an inverter’s “no load auto-shutdown” feature through an external circuit so that the inverter may be kept running even with minor, below permissible loads at the output. The idea was requested by Mr. Em. Technical Specifications Thanks for your prompt responses and guidance. I was wondering […]
3 Sound Activated Switch Circuits Explained
In this post I have explained 3 simple sound activated relay switch circuits which can used as a module for any system that might be assigned to trigger by detecting some kind of sound pressure level. Or simply applications such as a voice activated alarm security circuit. 1) Circuit Objective Utilizing this basic sound activated […]
ACS712 Current Sensor Circuit Diagrams and Datasheet
Here we are going to learn one cool and very important current sensor device which we call ACS712. This small chip that look just like a normal 8-pin IC, is actually able to sense current from any load and give us a proportional analog voltage output which we can easily feed to Arduino or any […]
Single LM317 based MPPT Simulator Circuit
To make this simple MPPT circuit we first modify a standard LM317 power supply circuit into a buck converter then configure it with a solar panel for implementing an MPPT function. Modifying a LM317 Power Supply into an MPPT Solar Optimizer In our previous article I have explained how a standard LM317 power supply could […]
How to Calculate Ferrite Core Transformers
Calculating ferrite transformer is a process in which engineers evaluate the various winding specifications, and core dimension of the transformer, using ferrite as the core material. This helps them to create a perfectly optimized transformer for a given application. The post presents a detailed explanation regarding how to calculate and design customized ferrite core transformers. […]
