Speed Control Using Slip Energy Recovery Schemes: The foregoing discussion makes it very clear that the methods of voltage control and rotor resistance control have poor efficiency, particularly at low…
Control of DC Electric Motor: A separately excited DC Electric Motor is very versatile as a variable speed motor. Its speed can be varied by varying the applied voltage to…
Three Phase AC Voltage Controller: To control the current and voltage of three phase loads, Three Phase AC Voltage Controller are required. The single phase controller described previously can be…
Cycloconverter: A variable frequency supply for feeding a three phase motor can be obtained from a cycloconverter which operates on a 50 Hz supply and provides a variable frequency supply…
Voltage Control Techniques for Inverters: It has already been mentioned that Inverter Control providing a variable frequency supply to three phase motors should be capable of providing a variable voltage.…
Charging a Capacitor in Inverter: Charging a Capacitor in Inverter - Inverters are static power converters for converting dc to ac. By controlling the conducting periods of the thyristors it…
Base load and Peak Load on Power Station: The changing load on the power station makes its load curve of variable nature. Fig. 3.13. shows the typical load curve of…
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…
