With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.

A regulated DC power supply is also known as a linear power supply, it is an embedded circuit and consists of various blocks. A regulated power supply (RPS) is an embedded circuit, used to convert unregulated alternating current into a stable direct current by using a rectifier. Regulated Power Supply – Block Diagram. A linear power supply, or an adjustable power supply, or a variable power supply can be a regulated power supply.

An important point to keep in mind is, a regulated power supply is not always designed for just constant output voltage, it may be designed for constant output current. Some power supplies even include fuses that will blow if the surge of electricity is too great, as a way of protecting the equipment.

Figure 1: Basic diagram block diagram of a linear power supply with regulation – Image Credit. In a regulated power supply, the input to the regulating device is usually higher than expected output.

This allows the circuit to work with a wide range of input voltages while giving out a constant output. Get Instant Quality Info Now!

What is a regulated power supply ? Today, there are literally thousands of dedicated IC voltage regulators. Nearly every manufacturer has a range of regulators to suit nearly every requirement. Firstly they come in a variety of voltage ranges fromand 15V for LM340.

I went online and found a lot of websites which offered plans and instructions. I chose this design because it is relatively simple. While this power supply type isn’t used as prevalently today, it’s still the best choice for applications that require minimal noise and ripple. Converts unregulated AC quantity to regulated DC quantity.

In this section of Electronic Devices and Circuits. Unregulated Power Supply. Well, which one’s actually ideal for use depends on your requirements. Variable regulated power supply.

Having a variable regulated power supply that can output precise voltages in the 0. Volts interval is a great add-on for any electronics lab. Especially when it’s a high power supply that can handle as much as 20Amps of current.

The Power Supply Experts. DIY single-rail linear regulated power supply (PSU). A low ripple regulated DC power supply designed based on transistors is shown here.

Such transistor voltage regulators are suitable for application where high output current is required. Shop with confidence on eBay! This dual regulated power supply produces the maximum DC output voltage 6. Some devices works in battery power with voltages ranging from 1. V and the minimum DC voltage 1. V to 9V, but majority of the devices can be directly plugged into a power plug. Feedback is implemented with Rand R so this is a regulated power supply.

I designed and built a simple DC regulated power supply to drive the 300B filaments in the "Unnecessarily Complex 300B Amp" some time ago. Since then I have had a number of requests to buy PCBs for this circuit.
