Ac Power Supply Definition

An example of sine wave ac is common household utility current in the ideal case.

Ac power supply definition.

Some ac waveforms are irregular or complicated. It converts the alternating current from your wall outlet into a continuous form of power called direct current that the computer components require. It also regulates the voltage to an adequate amount which allows the computer to run. Power in an electric circuit is the rate of flow of energy past a given point of the circuit.

A power supply is a hardware component that supplies power to an electrical device. The term usually pertains to devices integrated within the component being powered. 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. In alternating current circuits energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow.

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. These are called. Square or sawtooth waves are produced by certain types of electronic oscillators and by a low end uninterruptible power supply when it is operating from its battery. This is called an isolation transformer other ac power supply transformers do not provide mains isolation.

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. 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. 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. 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.
