Modified Alternator design for Automatic Voltage Regulation

For the proper operation of electrical equipment, it is important to have input voltage within permissible range (230V±5%). The input voltage supplied by the utility is generated by alternators. It is a well-known fact that the alternator terminal voltage decreases with an increase in load. In order to meet the consumer’s requirement, one needs to regulate the voltage of an alternator. This paper proposes the manner in which the design of the alternator can be modified to minimize the voltage regulation of an alternator.
