Use of PWM as a switching technique Pulse Width Modulation (PWM) is a commonly used technique for generally controlling DC power to an electrical device, made practical by modern electronic power switches. However it also finds its place...
Most of us are more comfortable with 1, 2, 3, 4… rather than 001, 010, 011, 100. We mean to say that we will need a decimal coded output in many cases rather than a raw binary output. We have many counter ICs available but most of them...
We know that the unidirectional device like an SCR includes the characteristics of the reverse blocking current because it stops the flow of current in a reverse-biased state however for several applications, this kind of current control...
3 Reasons why are LEDs being used as a source of light compared to HID lamps LEDs don’t have a filament to burn out or break; therefore, they last much longer than conventional bulbs. Given that a very small semiconductor chip runs an...
Introduction to LED An LED or Light Emitting Diode is a simple PN junction diode, made of material with larger energy barrier. As the supply is given to the LED junction, the electrons move from the valence band to the conduction band....
In industrial applications, two forms of electrical energy Direct Current (DC) and Alternate current (AC) are used. Constant voltage and constant current AC is directly available. However, for different applications, different forms, different...
Servo implies an error sensing feedback control which is utilized to correct the performance of a system. It also requires a generally sophisticated controller, often a dedicated module designed particularly for use with servomotors. Servo...
What is an RFID tag? The RFID tag is a microchip with an antenna in a compact package. The Tag can be attached to the object to be tracked through Radiofrequency. The Tag’s antenna picks up the signals from the RFID reader and then returns...
Temperature is the most often measured environmental quantity and many biological, chemical, physical, mechanical and electronic systems are affected by temperature. Some processes work well only within a narrow range of temperatures. So...
Definition A brushless DC motor consists of a rotor in the form of a permanent magnet and stator in the form of polyphase armature windings. It differs from the conventional dc motor in such that it doesn’t contain brushes and the commutation...
