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 […]
Motion Detector Circuit using Doppler Effect
The motion sensor circuit explained in the article works by using doppler shift principle, in which the moving target is detected through the continuously varying frequency, reflected from the moving […]
