Ac Power Supply Definition

Irregular ac waves are produced by audio.

Ac power supply definition.

These are called. Some ac waveforms are irregular or complicated. It also regulates the voltage to an adequate amount which allows the computer to run. 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.

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. An example of sine wave ac is common household utility current in the ideal case. 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. It converts the alternating current from your wall outlet into a continuous form of power called direct current that the computer components require.

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. 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. 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.

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. A power supply provides components with electric power. A power supply is a hardware component that supplies power to an electrical device. Power in an electric circuit is the rate of flow of energy past a given point of the circuit.

The term usually pertains to devices integrated within the component being powered.
