Ac Power Supply Definition

In alternating current circuits energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow.

Ac power supply definition.

The portion of power that averaged over a complete cycle of the ac waveform results in net transfer of energy in one direction is known as. It receives power from an electrical outlet and converts the current from ac alternating current to dc direct current which is what the computer requires. Irregular ac waves are produced by audio. A power supply is a hardware component that supplies power to an electrical device.

An ac power supply typically takes the voltage from a wall outlet mains supply and uses a transformer to step up or step down the voltage to the desired voltage some filtering may take place as well. Alternating current ac is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current dc which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences and it is the form of electrical energy that consumers typically use when they plug kitchen. It converts the alternating current from your wall outlet into a continuous form of power called direct current that the computer components require.

Some ac waveforms are irregular or complicated. The term usually pertains to devices integrated within the component being powered. These are called. For example computer power supplies convert ac current to dc current and are generally located at the rear of the computer case along with at least one fan.

This is called an isolation transformer other ac power supply transformers do not provide mains isolation. The power supply unit is the piece of hardware that converts the power provided from the outlet into usable power for the many parts inside the computer case. A power supply provides components with electric power. An example of sine wave ac is common household utility current in the ideal case.

It also regulates the voltage to an adequate amount which allows the computer to run.
