There is no exact answer for this, sense the actual circuit should be designed based on many factors. But, in general, you would have a transformer that steps the AC voltage down to an appropriate level. Then the low voltage AC would be run through a rectifier circuit which would output a DC signal. And finally, this DC signal would be conditioned using filters.
Some of the factors that would need to be taken into consideration before designing the actual circuit would be the supply voltage, the amount of output power, the quality of the incoming AC voltage, the desired quality of the output, how much circuit protection is required, the physical size of the circuit, cost, the type of load that will be connected to the circuit, and many more.

Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
How does 12v dc 1.5 amp power adapter differ from 12v dc 3 amp power adapter?
12v 1.5amp power adapter is 18 Watt, can't load more than 18W power consumption,3amp power adapter can load 36W.
Can you use a 9v dc power adapter on a device that requires a 10v dc?
No. The 9 volt DC adapter has a built in bridge rectifier that changes the AC to DC. Usually it is a half wave rectifier but on some more of the expensive adapters a full wave bridge and capacitors will be used.
CAN YOU STEP DOWN 36 volt dc to 12 volt dc using batteries?
can ou step down 36 volts dc to 12 volt dc using batteries
Can you run 12 volt DC adapter equipment with a 12 volt transformer?
The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.
Can a 9 volt 100mA ac adapter be substituted for a 9 volt DC 300mA adapter?
No. an AC adapter will not work for equipment that needs DC.
How can you build a DC wall adapter that has six nine-volt battery clip outs?
better yet get six 9 volt clip outs from radio shack and tie them to a wall adapter that is already on the market. Make sure you get an 9 volt adapter that will supply enought current to power all six devices at the same time.
Can I use a 9 Volt 1 Amp power adaptor in place of a 5 volt 1.2 Amp adaptor?
No, the voltage of the replacement adapter must always be IDENTICAL to the original adapter and the current of the replacement adapter must be the same or larger than the original adapter.Trying to use a 9 Volt adapter to replace a 5 Volt adapter will almost certainly completely destroy the device the moment you plug it in.You did not say whether the adapters provided AC or DC or the polarity if DC. Either way both the replacement adapter and the original adapter must be IDENTICAL in this respect.
Can I use 12V DC output universal ACDC adaptor with equipment that uses AC adapter 12VAC 2A?
There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.
Will a 120 volt AC to 12 volt AC adapter charge a 12 volt car battery?
No, the battery is DC not AC.
Can a 7.5 volt dc adapter be used for 9 volt dc speakers?
You may get some sound out of the unit but not at the fidelity that the manufacturer designed the speaker to produce.
Can you use a 9 volt dc adapter to power a device that calls for 10 volts dc?
Yes. However, the device me not run at its optimum capacity/speed. Other thing to take into consideration is that the polarity (+/-) of adapter and the receiving device must match.
Can a 9 volt DC adapter be used on a CD player that runs on 4.5 volts without damaging the player?
No, a 9 volt DC adapter can not be used on a CD player that runs on 4.5 volts without damaging the player.
Will a 120 volt AC to 12 volt AC adapter charge a car battery?
No, auto batteries are DC not AC.
Can you replace 12v vdc adapter by 12v vac adapter?
No, 12 volt AC is a different from 12 volt DC. Have a second look at the 12 AC volt adapter's output label. Most adapters contain a bridge rectifier in them that makes a conversion within the adapter. An example of this is in phone chargers.
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
What type of ac adapter does the ACDelco Jumpstart Compressor System portable power supply 59-255U require?
12 volt dc current output
