Unregulated Power Supply Circuit

Design of an unregulated power supply.

Unregulated power supply circuit.

This type of power supplies are normally used to supply power to current hungry loads for instance amplifiers control circuits irrigation systems alarm circuit. What is a regulated power supply. This output is given to a filter circuit which reduces the ac ripples and passes the dc components. In many of the circuit applications especially the ones using op amps a dual power supply becomes mandatory for enabling the and ground supplies to the 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. 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 a vast number of applications a simple unregulated power supply is sufficient. Regulated and unregulated power supplies are two such categories based on the type of output.

And the unregulated power supply circuit design skill is great in electronics learning. Before we get into the difference between a regulated and unregulated power supply let s first start with understanding exactly what power supply even means. Table of contents show all what is an unregulated power supply. The output of the transformer is a pulsating sinusoidal ac voltage which is converted to pulsating dc with the help of a rectifier.

The electrical characteristics of any power supply will depend on the circuit or circuits being powered but generally all unregulated power supplies consist of a transformer to step down the ac mains voltage to the required level as well as providing electrical isolation and a diode rectifier to provide an unstabilised output voltage. Key difference regulated vs unregulated power supply generally a power supply is a device or an electrical circuit that gives energy power to another electrical device. But here are certain disadvantages in using an unregulated power supply. Designing a simple dual power supply actually involves a just a center tap power supply and a bridge rectifier along with a couple of high value filter capacitors as shown below.

In a general sense a power supply is any device that supplies energy power to an electrical circuit. There are many types of power supplies. A regulated dc power supply is also known as a linear power supply it is an embedded circuit and consists of various blocks. Some called these power supplies that ac adapter.
