Derivation of Single Phase Quantity from Three Phase System: It will be seen later that auxiliary channels or pilot wires are used to transmit information from one end of the…
Methods of Discrimination in Power System Protection: Methods of Discrimination in Power System Protection are basically of two types: those which discriminate as to the location of fault, and those…
Voltage Variable Capacitors: VVC Operation - Voltage Variable Capacitors diodes (VVCs) are also known as variÂcaps, varactors, and as tuning diodes. Basically, a Voltage Variable Capacitors is a reverse biased…
Phototransistor Working: A Phototransistor Working is similar to an ordinary BJT except that its collector base junction is constructed like a photodiode. Instead of a base current, the input to…
Bridge Tied Load Amplifier: All of the power amplifiers already discussed have been single-ended (SE): meaning that they provide power to a load that has one terminal grounded and the…
Audio Power Amplifier using IC Amplifier Driver: The LM391 integrated circuit Audio Power Amplifier using IC Amplifier Driver contains amplification and driver stages for controlling an externally-connected Class-AB output stage…
