Abstract
The concept of the more electric aircraft is aimed at electrifying the mechanical, hydraulic, and pneumatic subsystems on aircraft. With increasing usage of power electronics, the architecture of onboard electrical power distribution systems becomes more complicated. Therefore, it is necessary to analyze the stability of the system. This article, first, presents and validates an impedance model of a permanent magnet synchronous generator as a source and dual active bridge converter as a load. These models are used for the stability analysis of a simple dc power system. In addition, two new control strategies are proposed to enhance the stability of the system. The stabilization effects of the new control strategies are verified with experimental results.
