Voltage Stabilizer in car or home

[puteh30]

hye... i new user (forumer)... help me....

1) -what is voltage stabilizer?
-application
-effect
- DIY circuit

2) fuse for voltage stabilizer?
why use fuse for car = 20A
motor = 10 A
home = 13A

tqvm....

A fuse isnt a voltage stabiliser, a fuse is over current protection.

2 common forms of voltage stabilisation are a zener diode or a voltage regulator chip
have a look at that link below for zener use

Zener use (http://www.reuk.co.uk/Zener-Diode-Voltage-Regulator.htm)

You have made no mention of what sort of voltage levels you want to stabilise, that would help so we can help you further :)

Do a wikipedia search on linear voltage regulators there's a good page of info

fuse in voltage stabilizer? use 10A or ???

fuse in voltage stabilizer? use 10A or ???

you use a fuse rating in a circuit appropriate for what current is being drawn
you still havent answered my question concerning voltages

to help you I need to know ....

1) input voltage to the stabiliser circuit?
2) stabilised output voltage needed for the equipment being supplied?
3) how much current does the equipment draw(need) ?

I say again ... a fuse DOES NOT stabilise voltage, a fuse is over current protection.

ooh...
1) input voltage = 12V
2) output voltage = 12V
3) current? i dont know...

to protect voltage stabilizer, use fuse 10A or ???

[davenn]

ooh...
1) input voltage = 12V
2) output voltage = 12V
3) current? i dont know...

to protect voltage stabilizer, use fuse 10A or ???

please .... if you dont know the current being used there is no way anyone can tell you
what the correct size of fuse to use

voltage stabilizer use at battery car.. for car the current is ?? fuse support for car ???

[davenn]

What is the stabilised voltage being used to supply ?

you are going to have power coming off the battery through the stabiliser circuit then to what ??
You need to give all the information else its very difficult for me to help you

cheers

A fuse is there to prevent 'too much' current flowing in a circuit. It is a last ditch control to stop components and wires actually melting. Until you specify what wire gauge and what other components may need protection then there is no answer to your fuse question.

To know what voltage stabiliser you need, you must decide the supply voltage, what volts you need and, for a current controlled stabiliser, what range of current it needs to supply. Do you want it to 'current limit' or to 'shut down' when the current demand is too high?

There are off the shelf units or designs to achieve almost anything you are every likely to need. But first you must ask the right question. (Sounds like some whacky adventure game but you know what I mean)

hey sophiecentaur

as you can probably tell I'm having a really difficult time getting any helpful info out of him/her, just a tad frustrating when doing what I can to help

The Q&A method just doesn't work well at this level. I just don't think it's fashionable any more to pick up a book and hack through a whole chapter to find what they want so they try to 'get by' asking loads of undirected questions.
I can sympathise, as we've all 'been there', but when I was a lad, there was no equivalent to the Internet and you just had to make the effort on your own.
I blame the media and a lot of rubbish teaching methods that suggest that anyone can do anything with no effort.
Ranting finished.

One method of voltage stabilization for AC voltages is to use a resonant transformer.

There are 120 and 240 volt 50 amp units using an alternative approach that requires much less copper and iron, used in motor homes. A microcontroller senses line voltage and changes the taps of an autotransformer by 5 and 12%.
