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
Dual power supply?
Dual power supply is used to describe a computer system with two power supply units (PSU's). This is to provide extra power for the computer's internal components.
What do you mean by dual tracking power supply?
the power supply is tracked by two's.
What kinds of electronics use a DC power supply?
Almost all digital electronics use a AC to DC power supply. Digital electronics cannot handle AC. all electronics device having battery powered are using DC power supply http://www.wzmicro.com
What is dual regulated power supply?
fu* ck of................
What is a DVE switching adapter?
A switching power supply adapter from Dee Van Electronics.
What Vcv Stands For in Electronics?
if you are reffering to Vcc than it means- It is the positive power supply used for TTL gates it is nothing but simple dc power supply. if we use CMOS than we use Vdd for indicating power supply these are method for indicating power supply.
What is Dual converters in power electronics?
Dual convertor means it converts ac to dc and again it converts dc to ac this phenomenon of converting two types of signal are in the same circuit is called as dual convertor
What does the power supply unit do?
It takes the mains supply and converts it to various lower voltages, suitable for the electronics in the computer. Usually 5v 12v 3v
What has the author Tomy Sebastian written?
Tomy Sebastian has written: 'Dual converter DC power supply systems'
If the power supply has blown what are chances that it has taken out the motherboard or something else?
Very unlikely. When a power supply "blows", a fuse is destroyed in the power supply. This is what the fuse was designed for. When a high voltage comes through, the fuse will burn out to prevent the surge from reaching the rest of the electronics. A surge protector does the same thing, but is better at catching voltage spikes than the power supply.
What does a dual voltage power supply do?
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
Where can one purchase a dual screen DVD player?
You can buy a dual layer DVD in various places. From entertainment stores to even some dollar stores, Most people don't recommend dual layer DVD's from dollar stores because they are usually not good, or don't have much space.
