To build a controlled rectifier or a phase controlled rectifier, the diodes in the rectifier circuits are replaced by SCRs. These circuits produce a variable DC output voltage
To obtain satisfactory and reliable SCR operation, it is necessary to provide protection against over voltages and over currents.
For proper operation of circuits using SCRs, the trigger circuits should supply the firing signal at precisely the correct
If an SCR is forward-biased and a gate signal is applied, the device turns on. However, once the anode current IA is above the holding current,
MCT (MOS-Controlled Thyristor) and SCS (Silicon Controlled Switch) are the low power devices belong to Thyristor family.
Three types of rays emits continuously from a radium material. These rays are known as alpha rays (a rays), Beta rays (p rays) and gamma rays (x rays).
The frequencies which are beyond the limit of hearing are called ultrasonic. The ultrasonic waves are of frequencies above 20000Hz (20 KHz).
The UJT Stand for Uni Junction Transistor. It has one PN junction and three terminals.
In electronics timers the output of the timing element is used as a trigger pulse for BJT, FET and UJT, the active devices element signal
The transducer may be defined as any device that convert the energy from one form to another, Most of the transducers either convert electrical
