plz how to loops in 110v ac to 250v ac stablizer and therir change over function and with out change over function circuits and tranceformer loops
plz help me
thanks
 

We speak English here. I cannot understand what you are talking about.

What is a "loop"?
What is a 110VAC to 250VAC stabilizer used for? Most of my electricity is 120VAC but the high power appliances use 240VAC. The voltages are very stable so I have never seen a stabilizer.
What needs to be changed over? Why and how?
What do you need help with? English?

Loops means tapings on auto transformer (winding loops in transformer), which is used to output near 240V from fluctuating mains input ranging from 110V-260V by connecting appropriate tap through relay switching. He needs to do it without taps and relays.

A taping is a audio or video recording. A transformer might have taps, not tape.
Why is the mains voltage fluctuating so much? My 120VAC mains fluctuates from 118V when all powerful appliances are running to 122V when they are turned off.
 

O.K. I missed a "p". Its tapping not taping.

In rural areas with local industries, voltages drop during daytime and raise high during nights when there is low load. it is due to line losses.
 

Here in Canada, almost all industries that use a lot of electrical power are in large cities. The voltage is controlled properly and does not fluctuate.

dear in pakistan 220v ac suply but in vilage suply down into 100v thats why 110v to 250v
and loops in transformer for 110v to 250v windings
i hop u understands
 

To eliminate tapping and relays

1. Rectify the input with full bridge and filter capacitor

2. Design a flyback converter(DC-DC) to have constant 240v DC

3.Make a inverter circuit in H-bridge configuration for sine output ( if load reuires sine input- INDUCTIVE LOAD)
or have a square output via push-pull configuration

I think haroon is asking for DVR (dynamic voltage regulator).

@haroonfreed,
It is probably better for you to use a transformer tapping-based stabilizer since that will be easier for you to design and work with. Additionally, constructing an entire two stage inverter for transformerless voltage stabilization may not present the cost savings you are probably looking for in replacing the transformer.

I agree with Tahmid. It would be far easier to implement an automatic stabilizer with taps than without taps.

yes sir you now help me
i think i desingn the taping tranceformer
you help me for how loops for taping and tranformer size their ciruit i use on those taping you may provide
thanks for helps me

sir i think i use taping transformer for this condition
but cannot use the programing ic technolgy and i cannot programme in ic this dificult job for me
but i use the taping tranceformer

To tell you the details of the transformer, you need to tell us about the control circuit. From your last post, what I infer is that you don't have that ready yet? Am I correct?

Refer to this if you are in need of such a system:
https://tahmidmc.blogspot.com/2014/02/automatic-voltage-stabilizer-ac-ac-with.html

If you do have a control circuit in mind or with you, if you provide more details, further help can be provided.

Hope this helps.
Tahmid.

sir i have no circuit and no adia but i think
i prepair in this trancformer size 1.50*2 core
yet you tell me how much taps loops and opreating circuit
provide me for this
another a circuit pcb shell be provide i can experiment on it and inform yoy
thanks
 

Point 1, ordinary incandescent light bulbs are very sensitive to over voltage, any slight over voltage shortens their life dramatically, it would be worth having a second (different type) of stabilizer for this circuit.
Point 2 you have given us your core dimensions, but not its type or power rating. If it is to be used for long periods (over 1/2 an hour or so) I doubt if its rated for more then 500W.
