What is adjustable DC power supply?
Adjustable DC power supplies are capable of delivering a variable output voltage or current. These adjustable power supplies fall into three categories: locally adjustable power supplies, remotely adjustable power supplies, and programmable power supplies.
How do you make a regulated power supply?
Step By Step Method to Design 5V DC Power Supply
- Step 1: The Selection of Regulator IC. The selection of a regulator IC depends on your output voltage.
- Step 2: The Selection of Transformer.
- Step 3: The Selection of Diodes for Bridge.
- Step 4: The Selection of Smoothing capacitor and Calculations.
What is a variable power supply?
A variable power supply is one which includes some means for the user to easily adjust the output voltage and sometimes the current. Adjustment is most often accomplished with a potentiometer, but may also be done with an analog control voltage, a digital input, an autotransformer, etc.
What is power supply circuit?
Definition: A power supply is an electronic circuit designed to provide various ac and dc voltages for equipment operation. Proper operation of electronic equipment requires a number of source voltages. Low dc voltages are needed to operate ICs and transistors.
What is regulated power supply circuit?
A regulated power supply (RPS) is an embedded circuit, used to convert unregulated alternating current into a stable direct current by using a rectifier. The main function of this is to supply a constant voltage to a circuit that should be functioned in a particular power supply limit.
What is adjustable dc power supply?
What is bench power supply?
A bench power supply is a standard piece of test and measurement equipment on every electrical engineer and circuit designer’s bench. They provide DC (direct current) voltage to a device under test such as a circuit board or other product being validated.
How do you make a good power supply?
To build this specific power supply, you will need the following:
- Power cord.
- SPST 120V toggle switch.
- Panel mount 120V neon lamp.
- 3 binding posts.
- Transformer with an input voltage of 120V and an output voltage around 24V to keep the Vin for the 7812 regulator above the minimum.
- Full-wave bridge rectifier.
How does a power supply work?
Most power supplies will take power from AC mains and convert it into a usable DC for use in electronic devices. During this process, a power supply is filling a number of roles, including: Transforming AC from a mains supply into a steady DC. Preventing any AC from interfering with a DC supply output.
How to make a high voltage power supply?
– Soldering Iron and solder – Hot Glue Gun and Glue Sticks – Wire Cutters – Wire Strippers – Nedle Nose Pliers – X-Acto Knife – DC Volt Meter (optional)
What does a power supply do in a circuit?
What is the main function of an AC/DC power supply in an electronic circuit? An AC/DC power supply’s primary function is to convert alternating current (AC) into a steady direct current (DC) voltage, which may subsequently be used to power various electrical devices.Alternating current is used to carry electricity from generators to end consumers through the electric grid.
How to make adjustable voltage power supply simple IC LM317?

How to make variable power supply circuit with digital control?
Variable Power Supply with Digital Control. A variable power supply circuit is built with variable positive voltage regulator LM317, CMOS decade counter IC CD4017, timer IC NE555 and fixed negative voltage regulator LM7912. The AC supply is fed to the transformer which is stepped down to 12V AC. The output of the transformer is rectified using
