This regulated power supply can be adjusted between a few volts and 15v with p1 and with p2. Each may have its own regulated supply e g. Simply said it is a power supply that can adjust the output voltage or current. Here r1 refers to 240 ohm r2 could be a 22k pot and rc may be calculated using the following formula for achieving the required current control feature.

Smoothing a filtering circuit to smoothen the variations present in the rectified output. A regulated power supply converts unregulated ac alternating current to a constant dc direct current a regulated power supply is used to ensure that the output remains constant even if the input changes. For example many complex circuits need different voltage levels for different electrical and electromechanical parts. But it still has the same characteristics as a fixed regulated power supply.

It will keep a stable voltage when it has any load. Approaches using integrated circuits both the 7800 series of integrated circuit regulators and the lm317 adjustable regulator. The block diagram of a regulated power. The lm 317 series is adjustable to three terminal positive voltage regulators.

A variable power supply is one which facilitates the user to vary and adjust the desired output voltage and output current. Load the load which uses the pure dc output from the regulated output. Variable power supply circuit. Power supply using discrete components in section b9 3 4 of your text we used the zener diode as the voltage controlling device in the design of a regulated power supply.

What is a regulated power supply. A regulated dc power supply is also known as a linear power supply it is an embedded circuit and consists of various blocks. Transistor variable power supply 1a 0 30v. Usually a potentiometer is used for voltage adjustments.

The variable power supply circuit is equipped with an adjustable voltage regulator to adjust the output according to the output. What is a variable power supply. Stabilized adjustable power supply 0 15v 5a received by email 04 27 2008. Block diagram of a power supply unit.

This power supply circuit is highly stabilized that its output voltage will drop only 0 005 even though the. Regulated power supply block diagram. Regulator a voltage regulator circuit in order to control the voltage to a desired output level. Sumit thakur ece seminars regulated power supply seminar and ppt with pdf report.

Regulated power supply is an electronic circuit that is designed to provide a constant dc voltage of predetermined value across load terminals irrespective of ac mains fluctuations or load variations. It is highly efficient in protecting circuits that are complex and complicated. Be used in the power supply unit because each section of the circuit has its own regulator.
