Electrostatic Precipitator (ESP) - Construction and Working Principle: Electrostatic Precipitator is located between the boiler and the chimney, it extracts the fly ash from the flue gases and thus prevents…
Pressurised Fluidised Bed Combustion System (PFBC): Pressurised Fluidised Bed Combustion (PFBC) system is used for large coal burning applications. The operating efficiency of PFBC is increased by introducing differential air…
Astable Multivibrator Definition and its Working: The multivibrator circuit which has no stable state is called the astable multivibrator. The two states of operation of astable multivibrators are quasi-stable (temporary)…
What is Switching Circuit? In practice, we often need making (switching on) and breaking (switching off) of an electrical circuit. It is also desirable and sometimes essential that the switching…
Single Phase Full Bridge Inverter: The main drawback of half-bridge inverter is that it requires 3-wire dc supply. This difficulty can, however, be overcome by using a single phase full…
What is a Power Converter? Solid-state power converter are employed for obtaining the approÂpriate form of electrical energy such as direct current or adjustable-frequency alternating current (required to operate most…
Light Activated SCR (LASCR) - Symbol, Construction and Operation: Light activated SCR is just an ordinary SCR except that it can also be light triggered. Most LASCRs also have a…
Shockley Diode Equation, Symbol, Operation and Applications: The four layer diode, also called the Shockley diode after its inÂventor Willian Shockley, is essentially a low-current SCR without a gate. It…
