While experimenting with a 300V DC to 220V AC inverter circuit, I noticed a strange overunity phenomenon which appeared to be like the generation of free energy from the inverter transformer. Recently while experimenting with a high voltage converter circuit, I was quite astonished to see a strange overunity kind of occurrence wherein the inverter […]

Li-Ion batteries are one of the most advanced […]
Understanding Scalar (V/f) Control for Induction Motors
In this article I will try to explain how scalar control algorithm is implemented for controlling induction motor speed with relatively straightforward calculations, and yet achieve a reasonably good linearly variable speed control of the motor. Reports from many top market analysis reveal that induction motors are the most popular when it comes to handling […]
Understanding Pull-Up and Pull-Down Resistors with Diagrams and Formulas
In this post I am going to explain pull-Up resistor and pull-down resistor, why they are commonly used in electronic circuits, what happens to electronic circuits without Pull-Up or Pull-down resistor, and How to calculate Pull-Up and Pull-down resistor values and finally we will see about open collector configuration. How Logic Inputs and Outputs Work […]
Digital Buffer – Working, Definition, Truth Table, Double Inversion, Fan-out
A buffer stage basically a reinforced intermediate stage which allows the input current to reach the output without getting affected by the output loading. In this post I will try to explain what digital buffers are, and we will be taking a look at its definition, symbol, truth table, double inversion using logic “NOT” gate, […]
