Variable Regulated Power Supply Circuit Diagram
Here is the circuit producing variable voltage power supply designed using fixed voltage regulators.
Variable regulated power supply circuit diagram. Adjustable power supply circuit. The fixed voltage regulator is used to offer fixed voltage at the output terminal and does not depend upon the input voltage supplied. It s based on the lm317 that controls a few high power bipolar transistors connected in parallel to achieve a 0 30v voltage interval and a maximum current of 20amps. For this article i m going to show you my variable regulated power supply built from scratch the circuit diagram i ve used and a few safety tips.
Simply said it is a power supply that can adjust the output voltage or current. Variable power supply circuit from fixed voltage regulator. This circuit is not an absolute novelty but it s simple reliable rugged and short proof featuring variable voltage up. But it still has the same characteristics as a fixed regulated power supply.
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. Transistor variable power supply 1a 0 30v. A variable dc power supply is one of the most useful tools on the electronics hobbyist s workbench. What is a variable power supply.
