Stability study and simulation analysis on aircraft transformer rectifier unit (TRU) with constant power load (CPL)

The electronic converters have been extensively applied in the distributed power system, which will impact to the power system´s power supply quality and its stability since the non-linear characteristic of the electronic converters. However, the distributed configuration has been commonly used in modern aircraft power system. The models of constant power loads are established in this paper. Based on these, the impacts of the loads on the aircraft power system are analyzed with the small-signal approach. Finally, the simulation results are presented here which coincide with theoretical analyses
