How does a voltage stabilizer work?

                              How does a voltage stabilizer work? 

We use voltage stabilizer in house for tv, fridge etc. But how does it work? It is believed that stabilizers will keep the electronic tools safe from voltage surges. Here is how ------
Electro mechanical regulators usually called voltage stabilizers , have also been used to regulate the voltage on AC distribution lines. These regulators operate by using a servo- mechanism to select the appropriate tap on an auto transformer which has multiple taps.
They do it by moving a wiper on a continuosly variable auto transformer. If the output voltage is not in the acceptable range, the servo mechanism switches connections or moves the wiper to adjust the voltage into the acceptable region.
The controllers provide a dead band wherein the controller will not act, preventing the controller from constantly adjusting the voltage as it varies by an acceptably small account.
