The use of virtual flux estimation in aerospace starter-generator systems

This study explores how virtual flux estimation may be applied to the grid synchronization of an aerospace S/G system. This technique is used to make the converter more resilient to the grid distortion to be expected on an aircraft distribution bus. The performance of the proposed system is assessed in simulation and hardware. It is demonstrated how using the virtual flux technique the converter is able to maintain synchronization with the grid under the maximum distortion conditions permitted by aerospace power quality standards.
