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...
The application of predictive current control to a multilevel converter is investigated in an aerospace starter-generator system. The use of a multilevel inverter with predictive current control enables the system to reduce the harmonic distortion in the current waveform when compared to a conventional Field Orientated Controller. It is important that the power converter is optimized to control the...
This paper proposes an alternative method for starting an aerospace gas turbine, temporarily driving its existing low inductance wound-field generator as a starter-motor using back-to-back connected, diode clamped inverters. This approach will result in a net weight saving as the existing pneumatic starter is now not required. A prototype converter is constructed and tested upon an aerospace generator,...
