Abstract :
In high speed aircraft, Ultra high-speed generator´s safe operation and smooth power supply to load would be threatened by mismatching between open-loop generator and the fickle load condition. In this paper, a power converter with paralleled energy-matching link was developed, which can broaden safe operation zone and ensure generator´s safe operation as well as load´s smooth power supply under relatively light load conditions. This power converter can also ensure power supply voltage following under relatively heavy load conditions. The validity was verified by experiment results.
