Abstract

With the development of more electric/all electric aircraft, Variable Frequency AC Generation SYSTEM (VFAC SYSTEM) has been widely used in large civil aircraft. In this paper, the VFAC generator system based on the Dual-Stator Winding Induction Generator(DWIG) is discussed, which has the feature of high power output per single generator and high fundamental frequency. Generally, the switching frequency of the high power device does not exceed 5 kHz, so how to ensure the quality of the system output voltage and the dynamic performance with limited carrier ratio becomes the focus of the study. In this paper, the Specific Harmonic Elimination Pulse-Width Modulation (SHEPWM) is adopted and the carrier ratio changes with different fundamental frequency range, thus the system's switching loss is limited while the output voltage's quality remains good. As SHEPWM does not have the function of real-time control, Flux Trajectory Tracing Control (FTTC) is adopted to improve slip-frequency control. Simulation and experiment prove the correctness and effectiveness of the method proposed, which can be also used for medium frequency inverter.
