Step up Chopper - Definition, Circuit Diagram and its Working Principle: In a step-down chopper the output voltage lies between zero and supply voltage. However, there are techniques by which the output of a chopper…
Step Response of an Amplifier: An alternative criterion of amplifier fidelity is the response of the amplifier to a particular input waveform. Of all possible available waveforms, the most generally useful is the step voltage.…
Step Function Response: The step function response consists of applying an instantaneous change in the control means and then recording graphically the result of the change on the measured variable. This graphical record obtained in…
Step Down Converter: A step-down switching regulator, or Step Down Converter (also termed a buck converter), produces a dc output voltage lower than its input voltage. The basic circuit arrangement for a step-down converter is…
Step Down Chopper with RLE Load Working Principle: The choppers are widely employed for speed control of dc motors in industrial and traction drives. Figure 27.30 (a) shows the basic Step Down Chopper with RLE…
Steam Turbine Working Principle and Types: Steam turbines are one of the most versatile and oldest prime movers that transform the potential energy of the steam into kinetic energy and later in turn transformed into…
Steam Turbine Efficiency: The overall Steam Turbine Efficiency is quite low (about 29%) due mainly to two reasons. Firstly, a huge amount of heat is lost in the condenser and secondly heat losses occur at…
Steam Power Plants Interview Questions and Answers: 1. Why overall efficiency of a thermal power plant is very low ? Ans. In a steam power station, more than 50% of total heat of combustion is…
Steam Condenser - Definition, Working Principle and Types: Steam condenser is a device in which the exhaust steam of a turbine is condensed by means of cooling water below atmospheric pressure. By decreasing the exhaust…
Steady State Stability of Drive: Equilibrium speed of a motor-load system is obtained when motor torque equals the load torque. Drive will operate in steady-state at this speed, provided it is the speed of stable…
