DC power supplies use AC mains electricity as an energy source.A rectifier is used to convert the transformer output voltage to a varying DC voltage, which in turn is passed through an electronic filter to convert it to an unregulated DC voltage.

Use of DC power supply?

DC power supplies are categorized by the mechanism used to convert and transfer the input power to the output power. There are three main categories: Linear power supplies accept AC inputs and provide one or more DC outputs for a wide variety of computer and industrial applications.

DC power supply circuit?

An Unregulated Power Supply is the simplest of power supplies to construct. Nearly all electronic devices and circuits require some form of a DC power source for their operation either from a battery, solar cell or as a mains power supply. ... Rectification is the process of converting AC power into DC power.

Where is DC power supply used?

DC power is widely used in low voltage applications such as charging batteries, automotive applications, aircraft applications and other low voltage, low current applications. All solar panels nowadays produce DC power,

DC power cable?

A DC connector (or DC plug, for one common type of connector) is an electrical connector for supplying direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable.

3 types of power supply?

There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching. A fourth type of power supply circuit called the ripple-regulated, is a hybrid between the “brute force” and “switching” designs, and merits a subsection to itself.

Switching dc power supply?

A Switching DC power supply (also known as switch mode power supply) regulates the output 
voltage through a process called pulse width modulation (PWM). The PWM process generates some high frequency noise, but enables the switching power supplies to be built with very high power efficiency and small form factor.
