VOLTAGE REGULATOR USING OP-AMP
ABSTRACT
In real life situations, we come across many scenario where we require a constant output voltage even though the input voltage is varying randomly .Voltage regulator is the device which produces constant output voltage for varying input. Generally in many of the household appliances like TV, refrigerator uses stabilizers to supply constant voltage to the appliance in spite of the fluctuations in input voltage. In this, we are going to explain the working of a voltage regulator using IC748 and transistors, resistors and capacitors.
INTRODUCTION
In most of the practical situations, the output of some systems required to be maintained at a constant level. So a voltage regulator serves the purpose. A voltage regulator is designed to automatically maintain a constant voltage level. A voltage regulator may be a simple “feed forward” design or may include negative feedback control loops. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages. Electronic 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. Here in this circuit we are constructing a circuit using op-amp and transistors.
COMPONENTS REQUIRED
1)µA 741 op-amp
2)Transistor(2N3055)
3)Zener diode
4)Potentiometer
