To convert DC (battery) to AC to run household appliances you need an "inverter". Because they are usually hooked up to a car battery (12V) they can't provide too much power. Usually enough to run lights, a small refrigerator, TV or laptop computer OR similar low power equipment.

Why transformer can not be used in dc supply?
The transformer cannot be used in the DC supply because it keeps on alternating its current, whereas the DC supply current should be constant.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
Why doesn't transformer work on a DC supply?
to have transformer action there should be an alternating magnetic flux.but dc supply cannot produce alternating flux.
What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
Do pulse transformer is work on dc supply?
hthhrhr
What happens if a dc supply is given to a transformer under no load?
when dc supply is given to transformer at primary winding , the output at secondary winding will be zero.Because to induce voltage ,countnie changing flux is required ,that can not be obtained from dc supply...........
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
Does transformer works on DC?
I should think not
What will happen if transformer are connected to dc supply?
It will get core saturation
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
Why transformer do not operate with DC?
Transformer works with varying flux. DC won't create it. Only AC produce varying flux.
Can you step up or step down the DC voltage by a transformer?
You need alternating current for a transformer, for DC you would have to interrupt the power supply to make it effectively DC pulses.
