Abstract

This paper presents the development of a DC-DC buck converter based static excitation system for a micro-alternator. The IGBT based AC to DC converter is used as Front End Converter (FEC) followed by a buck converter to control the field voltage of micro-alternator. TMS320F28377S microcontroller is used for digital implementation of the Automatic Voltage Regulator (AVR). A proportional integral(PI) controller is used in the AVR. The proposed system is tested under various small and large disturbances like change in the reference voltage, 3-phase fault at generator terminal, and sudden load rejection to study the performance of the proposed excitation system.
