step up voltage transformer?

Question

looking for a dc 12 volt step up transformer. i can not find one on the internet. i asking if you would help me search the internet for one. first one to post a link with this will get the points. needs to step up to a maxmium of 96.
im drawing around 110 amps over 1 hour at 12 volts
i would like to have more voltage and less amps

DONT GIVE ME A STUPID ANSWER, OR A QUESTION!

Answer 1

You need to have a transformer company wind a custom tramsformer for you. You won't find a 110A 12V primary.

Answer 2

If you want to step 12 volts AC to 96 AC, you need a transformer with a primary to secondary winding ratio of 8. You then connect the 12 volts to the secondary, and will get 96V at the output.

The most accurate way to do this, is go to a transformer shop and ask them to do this. They will ask you for current requirements. If this is not an option, go to a hardware store and ask for a 120V to 15V (or whatever value is closest) transformer.

Keep in mind that while voltage is multiplied, current is divided, so that at the end you get the same power. So, if you have a transformer with n=8:

V=12*8=96 volts
I= 110/8=13.75 amps

Answer 3

A stupid question deserves a stupid answer. A transformer does not work on DC--only AC. Therefore, what you are looking for is not a transformer but a converter. This changes the DC to AC then goes through a transformer as AC and finally reconverts it to DC if you want DC output--otherwise leaves it AC. Units like this are available everywhere to raise 12 volts DC to 110 volts AC. DO YOUR OWN RESEARCH. And finally the question you didn't want asked: WHAT MAKES YOU SO ARROGANT?

Answer 4

I answered before and it was correct, not stupid.

You cannot directly transform DC. It must be turned into AC using an inverter. You can then step up the voltage using a transformer.
Finally rectify the AC to get DC again.

Sorry you don't like the answer but that's how it's done.
If you want to do it by switching the DC, fine, but now you're changing the duty cycle and your current is going to have to increase to deliver the same amount of power. Oh, and I wonder how many thousand volts you're going to get as the magnetic field in that transformer comes crashing down when you switch the DC off. Ever hear of a spark coil?

I suggest that you don't insult those who are trying to help you.

Answer 5

A trick question. A transformer needs a change in amplitude of the voltage applied to work. A DC voltage that causes a current to vary in magnitude but not change direction is still a DC voltage. The changing DC current provided by a DC voltage that does not change direction is all that is needed to make a transformer work.

Answer 7

Install a 125 volt 30 amp receptacle where the oven outlet is and rewire for a neutral in the breaker panel.

Answer 8

You need a converter not a transformer. Here is a DC to DC converter.

Answer 9

Easiest is to get from normal charger and modify the circuits. One with 110Vac and 12Vdc output.
Modify the circuits inside.

i had a similar lab to do for one of my classes, one of the hardest labs too..... sryy
