AC to DC, no prob, but DC to AC??????

You need a circuit called an inverter.  These are available to plug into your 12 V socket in your car.  However, use these with the engine running or you could easily drain your battery.

AC in and DC out.\n\nA diode only allows current to flow in one direction and blocks it if it is wrong.\n\nthe diodes in the bridge are connected together so that the +V current flows in One direction. the bridge .....( I cant be bothered)\n\nwikipedia has the answer...\n\nhttp://en.wikipedia.org/wiki/Bridge_rectifier

What voltage dc, or do you need to be able to vary it?  What current capacity do you need?  What ripple voltage is acceptable?

There are several converters. Try this, for example...

Try pa powerport ! They have lots of links to things in P.A. I found lot"s of stuff there!

Need to know a need or application. AC voltage by definition is bipolar. What are you trying to do?

No, not really. you'd probably end up overloading the the computer even if you could plug in anything.

AC & DC of the same voltage can push the same amount of current through a wire.  In regular use however, we never see them at the same voltage.  There is no DC power transmission, and no one makes AC batteries.\n\nYour portable stereo either has an adapter to lower the 120VAC house voltage & convert it to DC, or has circuitry to raise your 12VDC car voltage & convert it to AC.  The former is more likely.  Since homes have 120VAC power, most appliances that use lower voltage DC have adapters, either built-in or external.

no that is why our electricity is ran house to house in ac.  it is safer to operate ac and also more energy efficient.

Here are some sites that may help.  Both have circuit examples utilizing LVDT's.  Hope this helps.

This does nto seem to make much sense unless the battery is so old that even at a full charge it does not have enough battery power to run all of the necessary parts of your laptop. You can try this. go into: START, CONTROL PANEL, POWER OPTIONS, under POWER SCHEMES you can pick PORTABLE LAPTOP, then you can check the options below of how you want the laptop to run while plugged in to AC and how to run plugged in to BATTERY POWER.  Hope this helps...\n\nIf neither of these situations fixes your issues, then you may need to go into your SYSTEM Properties and check out to make sure all your devices are performing okay..

You'll need to provide a little more information in order to have your question answered properly.  AC or DC? Input voltage?  Fixed or variable output voltage? If variable, over what range? If fixed, what is the desired output voltage?  Output current?  How critical is the load regulation?\n\nAs you can see, the answer to your simple question can be a bit complicated :)

The answer is a bit too long to go on this site.\n\nIf you would like to correspond by private message or by email I can help you.\n\n\nThere's one soulution here http://www.davidbridgen.com/5vdet.htm

There are so many converter softwares out there...goto download.com and search it...

Inverter: DC to AC\n\nRectifier: AC to DC.\n\nthey do opposite functions.

Ok break it down:\n1) A power supply converts AC power (110 in the states) to some other required voltage. For this (lab) project I'd presume a DC regulated voltage from, say 1.5 to 15V something like that.\n\n2) Digital and programmable means you'd control the output voltage with some sort of digital signal like up/down buttons, a keypad, or a PC hookup.\n\n3) You are supposed to use an 8051 to accomplish this.\n\nSo there are several ways to do this. One way would be to have the 8051 accept a command to set the voltage and produce a PWM signal. Let's say the PWM signal is a 5V output switched from 0 to 100%. You can use an RC filter to produce 0V to 5V from this signal. If your instructor is nice, you could argue that this meets the criteria -- especially if you use it to drive a pass transistor to develop some serious current (but your voltage is now 0V to 4.3V because of the BE drop).\n\nBut I'd instead use an op amp with gain X3 (plus a little extra) so that I got from 0 to 15.7V and then use the pass transistor. Another idea would be to use the voltage to drive a simple current source which would program a LM317 voltage regulator.\n\nWeb searches on things like LM317, PWM, and "pass transistor" are your friends here.

It seperates wear the wattage is going between the two seperate rails... It is like a house wired for 240.  Some of your outlets go to one rail in the electrical panel on 120 some to the other rail of 120.  Then yet others use both rails for 240.  In the computer power supply they never really combine both rails though, just split where the end of the line goes.
