This is an SMPS type voltage stabilizer for mains voltage (AC input and AC output). This is a new switching topology where PWM is made directly in AC-to-AC switching, without any harmonic distortion. In this topology there is no need to convert the AC input to DC and again convert it back to regulated AC output. This simplifies the design, reduces the component count and improves the efficiency and reliability. The power stage is an IGBT chopper control. The chopping frequency is around 20KHz which ensures absolutely silent operation and pure sine wave output (no waveform distortion).
 

Hi,
If you knows it so good _can you not share with us the circuit/documentation or usable details too pls?
Greetings!

no friend
i don't knows it so good. i want it
 
Aha;
My friend, it was_in my opinion_absolutely unclear,& not so writed & so on :)...

hai any boady know about the circuit for static stabilizer
 

a static voltage stabilizer is same like a Sinewave Inverter without Battery Part, convert the 230v to DC , convert it to 350V dc with PFC, Generate Sinewave from that, so the output will remain constant.

do u have any tested circuit of static stabilizer
 

no, i am at the design stage now
 

This is the latest state-of-the-art technology for automatically regulating your incoming voltage levels. It utilizes an IGBT based inverter topology to electronically modify the incoming electrical waveform to an ultra-pure sinewave with ideal voltage and power quality characteristics.
It performs what it claims.

I saw this product in mobile tower installation 3 years back.

Patent doccumentation for such a device,
DEVICE FOR TRANSFORMING AND STABILIZING A PRIMARY AC VOLTAGE FOR SUPPLYING AN ELECTRIC LOAD - Patent application.

Hi, can you recommend a very reliable manufacuturer for this product? I am look for 15kVa to 45 kVa. Thanks, Tk

We tested their product.
**broken link removed**

We varied input voltage throuhgout its whole range. It was supplying extremly stable output not even one volt fluctuation on digital multimeter. Inside there is one variable resistor to adjust required output voltage. We tried to import but due to regulations we could not. As cost is also high tried to reverse engineer it. It had a PIC16F72 inside two full bridge igbt drivers. One set was driving a stepdown transformer of 50 volts, which is in series to mains in turn add or subtract to main power.

This technology is similar to that used in grid-tied inverters to ensure their AC output voltage is just a little higher than their AC input voltage. It monitors and adds/subtracts from the power line rather than recreating a complete new output waveform. I would be intersted to know what the current sensor does other than possibly provide protection.

A similar technique has been used for many years. A specially crafted transformer couples the same AC voltage from primary to secondary but a thrd winding is used to restrict the magnetic coupling and hence the output voltage. It may not be as accurate as the method @sahu describes but it can be achieved with no active componebts at all, just capacitrs, inductors and resistors.
