Objectives

At the end of this lesson you shall be able to:
• explain the operative principles of BMPS & Inverter

Stabilizer:
A Stabilizer is a thing or device used to maintain something or a quantity steady or stable. There are different
types of stabilizers based on the quantity they are used for maintaining stability. For example, a stabilizer used
for maintaining the voltage quantity stable in a power system is called as voltage stabilizer.

Voltage Stabilizer

Voltage stabilizer is designed for maintaining the stable voltage level to provide a constant supply in spite of any
fluctuations or changes in supply in order to protect the home appliances. Generally voltage regulators are used
to maintain constant voltage and these voltage regulators which are used to provide constant voltage to the home
appliances are called as Voltage Stabilizers.

There are different types of voltage regulators such as electronic voltage regulators, electromechanical voltage
regulators, automatic voltage regulators and active regulators. Similarly, there are different types of voltage
stabilizers such as servo voltage stabilizers, automatic voltage stabilizers, AC voltage stabilizers and DC voltage
stabilizers.

Voltage Stabilizer Working
The working of the voltage stabilizer can be studied by considering the different types of voltage stabilizers, such
as:
AC Voltage Stabilizers

These AC voltage stabilizers are classified into different types such as Coil rotation AC voltage regulators,
Electromechanical regulators and Constant-voltage transformer.
