Regulator..A power supply is an important element of any type of electronic circuit. It provides the supply for the proper operation of the circuit. The successful operation of the circuit depends on the proper functioning of the power supply. Most of the electronic circuits require a smooth d.c. voltage as that of batteries. The power supply in a circuit tries to provide such a constant voltage. A block diagram containing the parts of a typical power supply and nature of the voltages at When a transistor is included in the diode circuit, a large load current can be supplied. The regulator performance is further improved by the addition of an error amplifier to detect and amplify the difference between the output voltage and the

voltage.reference source. 1C operational amplifiers make ideal error amplifiers. Complete voltage regulator circuits are available in integrated circuit form. Example 15.1 Draw the block diagram of a dc power supply and explain. Solution: The 3.181 Block diagram of a typical power supply The a.c. voltage is connected to a transformer. The transformer steps down the a.c. voltage down to the level required for the desired d.c. output. The rectifier converts a.c. voltage to a d.c. voltage. The filter circuit is used after the rectifier to reduce the ripple content in the d.c., to make it smoother. Still then the d.c. voltage usually has some ripple or a.c. voltage variation. This voltage is called unregulated d.c. voltage. A regulator
