AC is supplied to the input of DC power supply. One way to get to DC is to full wave rectify the AC sine wave. Basically you flip the negative side of the AC waveform to the positive side. You are left will all positive voltages varying from the peak voltage to zero and then back to peak. To make DC you need to smooth out the valleys and make them as close to the peak voltage as possible. You do this with various types of filters that usually involve a large capacitor. Once filtered you can use various circuits to either create a fixed DC output voltage or a variable output.

What is a treadmill motor and what can it be used for?
It can be used as a windmill generator, and it makes up for a good power supply. It can also be switched out for obsolete electronics.
What should be the setting for a dual voltage selector switch on a power supply when using a computer in the US?
The 110VAC to 125VAC range (not the 220VAC to 250VAC range).
Which laser printer component converts AC line voltage into the DC voltages the printer can use?
As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.
What are advantages power supply in computer?
The power supply converts the high voltage (e.g. 120VAC in US, 240VAC in Europe) alternating current house electricity supply down to the various different low voltage direct current supplies needed by different devices that make up the computer. These low voltage direct current supplies are tightly regulated in the power supply circuitry to prevent transients in the house electric supply from perturbing the computer's electronics as well as to compensate for variations in power demand as the different devices that make up the computer operate.
What is the difference between power electronics and digital electronics?
in digital electronics, engineers use low voltages like 5 or 12 or 24 volts but when they want to transfer electrical energy in high power which means high voltage and high ampere they use power electronics . in power electronics sometimes the transistor or diode or in power electronics language IGBT and thyristor can work in 10000 volt or higher voltages
