The quest cut through exit discuss how a personalized computing device (PC) power offer works and how a portable mp3 medication player (i.e. an iPod) power supply works. The root section of this field of study will detail how the power supplied to your PC is converted from an alternate(a) current (AC) to a direct current (DC), which is demand by the individual components in the computer. The second part of this report will discuss how an iPod battery works. 2.0 PC Power Suppl y 2.1 Principle Operation The power supply in a PC is typically located at the back and is macroscopic by a power cable 3-pin connector and a engine cooling system fan. [1] Connecting your PC to the mains supply in your house will deliver an AC current to the power supply unit.

Within the power supply unit the AC input will be converted to lower DC voltages by way of Switcher Technology. Typical voltages used deep down a PC are 3.3, 5 volts and 12 volts. Generally, the digital circuits require 3.3 and 5 volts. The components within a PC needing more(prenominal) power are the disk drives and cooling fans, which require 12 volts. ! In addition, PC power supplies in any study have a circuit called VSB (standby voltage). This circuit allows the computers ON button, when pressed, to pass over out a signal to the power supply to malefactor the machine on, even when it appears to be off. 2.1.1 AC Input fudge 1 lists AC input voltage and frequency requirements for uninterrupted operation. The power supply is capable of...If you want to get a full essay, prescribe it on our website: BestEssayCheap.com
