1.0 Introduction
Automatic Voltage Regulator (AVR) as the name implies, is a device intended to regulate voltage automatically that is to take a varying voltage level and turn it into a constant voltage level.
The AVR is a class of devices that provide constant voltage levels to prevent malfunction or damage to downstream electrical equipment.
Automatic Voltage Regulator is also known as stabilizer which is design and constructed with transform, circuit diagram and electrical component which monitor the level of the input voltage. Automatic Voltage Regulator is an auto-transformer and is a transformer with only one winding, the winding has at least three electrical connection point called taps.
The voltage source and the load are each connected to two taps, one tap at the end of the winding is a common connection to both circuit (source and load). Each tap corresponds to a different source or load voltage. And the ratio of secondary to primary voltage is equal to the ratio of the number of terms of the winding they connect to.
1.1 Purposes and Motivations
Automatic Voltage Regulator is a device that serves as intermediary to electrical/electronic equipment and its major purposes is to prevent malfunctions or damage to electrical equipments. And another major purpose of this AVR is to regulate varying voltage level automatically to a constant voltage. Having AVR as an intermediary device, it will motivate you in a such a way that you will not be having biasing mind in powering any device.
