 A PROJECT ON VOLTAGE CONTROL

 


The given project is successfully running and the circuit diagram given is 100% accurate.
Circuit Diagram:


Introduction:

qA voltage stabilizer is also called Automatic Voltage Stabilizer or AC Voltage Stabilizer or Voltage Regulator.
qActually an automatic voltage stabilizer is designed to automatically maintain a constant voltage level, with protections of equipment against voltage surges, over voltage, under voltage, smoothing impulsive noise.
qIt regulates the fluctuating input voltage and produces an constant  output voltage. The fluctuating range in different countries differs a lot. So, if our countries suffer from unstable voltage, we must equip voltage stabilizers for our appliances or a big AVR for our whole house .
qElectronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. In automobile alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line.
