Abstract

In order to improve the stability of high voltage direct current power supply system for more electric aircraft, reduce the cost and popularize the application of DC microgrid control technology in aviation. Firstly, this paper introduces the conventional PWM rectifier system based on the permanent magnet synchronous generator and its control strategy. Then, combining the advantages of the diode rectifier and active rectifier, a two-path hybrid rectifier system based on a permanent magnet synchronous generator is proposed, and the origin of the system topology and the corresponding control strategy is analyzed. Next, the small signal model of the power supply system is established, and the corresponding impedance model is further derived. Finally, based on MATLAB/Simulink, a simulation model of a two-path hybrid rectifier power supply system is built to verify the effectiveness of the proposed scheme and the accuracy of small-signal modeling, which provides a reference for the subsequent research on the power system architecture and stability of more electric aircraft.
