How to Design an Inverter – Theory and Tutorial
In this post I have explained the fundamental tips and theories which may be useful for the newcomers while designing or dealing with basic inverter concepts. I have explained more. What’s an Inverter It’s a device which converts or inverts a low voltage, high DC potential into a low current high alternating voltage such as […]
Generate Electricity from your Gym Workout
In this article I have explained the circuit implementation of an interesting concept of converting physical energy into electricity. Here I have explained a simple method of converting or channelizing the wasted gym workout energy into useful electrical energy. The idea was requested by one of the keen members of this blog, let’s know more: […]
Homemade Solar MPPT Circuit – Poor Man’s Maximum Power Point Tracker
MPPT stands for maximum power point tracker, which is an electronic system designed for optimizing the varying power output from a solar panel module such that the connected battery exploits the maximum available power from the solar panel. Introduction NOTE: The discussed MPPT circuits in this post do not employ the conventional control methods like “Perturb and […]
High Voltage, High Current DC Regulator Circuit
We all are pretty familiar with the 78XX voltage regulator ICs or the adjustable types such as LM317, LM338 etc. Though these regulators are outstanding with their specified functioning and reliability, these regulators have one big disadvantage…. they won’t control anything above 35V. Circuit Operation The circuit presented in the following article introduces a DC […]
Make a Football Electricity Generator Circuit
The explained football electricity generator circuit was developed by me in response to the request sent by one of the readers Mr.Bright. Though I am not sure if the explained concept would actually give the intended results, it’s worth trying as it’s quite easy to understand and build. Designing the Generator There were three things that I had to consider while designing the […]
