HEY,ANYONE KNOWS CIRCUIT FOR VOLTAGE STABILIZER(AUTOMATIC CONTROL OF HIGH VOLTAGE)?

Such a thing would depend upon the requirements.

What kind of voltage (DC, AC) and current or power are you talking about?

A.C AND VOLTAGE
AS ONE SUCH DEVICE I HAVE USED IN MY COMPUTERR INPUT PIN

So you're wanting to regulate an AC voltage.

What is the peak or RMS value of the AC voltage that you wish to regulate?

What is the current or power required?

I DON'T KNOW EXATLY WHAT IS MEANING OF RMS VALUE.BUT NORMAL VOLTAGE RATING IS AT 230V,50HZ AC.
(It often goes at 280-290v.But due to stabilizer it controls to 240v)

RMS = Root Means Square.
A sinewave is sampled for voltage levels, the square root of those samples are calculated, then the samples are averaged together, and the result is squared.

If the sinewave is a perfect sine, an approximation of the RMS value can be calculated by multiplying the peak voltage by 0.707107.

If you already have a stablizer, but it's output voltage is incorrect, then it needs adjustment. The manufacturer should be consulted as to how or where you can get it repaired/adjusted properly.
