In order to provide power to aircraft control and meter equipment, Aviation Static Inverter (ASI) converts DC power to 115V/400Hz AC power. As a secondary power supply for modern aircraft, it is a significant part of aviation power supply system. Moreover, because of the high efficiency and low noise of ASI, it is widely applied in aircraft which is supplied by low voltage DC power. The structures and principle analyses of ASI are introduced in this paper. Single-phase and three-phases ASI are modeled in in Dymola/Modelica which can be applied in a variety of physical systems, FFT algorithm is also used to extract dynamic eigenvalue. The modeling and simulation results in Dymola platform can not only prove the correctness of the models, but also can reflect the dynamic and static performance of ASI. As a result, they provide reference for the design of aircraft power system.
