Driving a three phase motor on a single phase supply directly through ordinary methods can be difficult and dangerous. It requires accurately designed circuits for implementing the operations. Here I have tried to present one such PWM controlled three phase motor driver circuit. I have explained more. The circuit can be understood with the following […]

Maintenance Tips for Lead Acid Battery
In this post I have explained some of the crucial parameters related to lead acid battery maintenance tips for ensuring longer life to the device. The questions were asked by Mr. Raja Gilse, answered by me. What is Full Charge Voltage of a 12V Battery Question: What is the full charge volt of the 12 […]
Electronic Load Controller (ELC) Circuit
In this post I have explained a simple electronic load controller or governor circuit which automatically regulates and controls the rotational speed of a hydro-electric generator system by adding or deducting an array of dummy loads. The procedure ensures a stabilized voltage and frequency output for the user. The idea was requested by Mr. Aponso […]
I/V Tracker Circuit for Solar MPPT Applications
Optimizing power by tracking is the key feature which makes solar MPPT concept so unique and efficient, where the complex and non-linear I/V curve of the solar panel is tracked and switched for creating maximum optimal conditions for the connected load. The Circuit Concept I have been trying hard to design something that would in […]
Single Phase Variable Frequency Drive VFD Circuit
In this post I have explained a single phase variable frequency drive circuit or a VFD circuit for controlling AC motor sped without affecting their operational specifications. What is a VFD Motors and other similar inductive loads specifically do not “like” operating with frequencies that might be not within their manufacturing specs, and tend to […]
How to Protect MOSFETs – Basics Explained
In this post I will comprehensively explain how to protect mosfets and prevent mosfet burning in electronic circuits by following some basic guidelines related to correct PCB layout, and careful manual handling of these sensitive devices. Introduction Even after connecting everything correctly you find the mosfets in your circuit becoming HOT and blowing off within […]
