Transistor Monostable Circuits with Applications
In this post we will learn how to build a few simple monostable circuits using only transistors, and also learn how to make practical application circuits with them. If you […]
Regenerative Motor Acceleration Experiment
In this post we will learn about this special regenerative motor coil overunity phenomena which can be very interesting to the primary level experimenters like us. In this experiment a […]
DC Shunt Motor Controller Circuit using Variac
The simple DC shunt motor controller circuit presented in the following article uses a variac. This design facilitates an instant stopping of the motor at any stage with a flick […]
How an Autotransformer Works – How to Make
An autotransformer is an electrical transformer which consists of only a single, continuous, non-isolated winding, with tapped terminals across various points of the winding. The winding section between the taps […]
What is IGBT: Working, Switching Characteristics, SOA, Gate Resistor, Formulas
IGBT stands for Insulated-gate-Bipolar-Transistor, a power semiconductor which includes the features of a MOSFET’s high speed, voltage dependent gate switching, and the minimal ON resistance (low saturation voltage) properties of […]
