【 摘 要 】

A high-voltage direct current (HVDC) electric power system (EPS) has become an attractive power distribution architecture for the more electric aircraft. The structure of a typical HVDC parallel EPS based on the permanent magnet synchronous machine (PMSM) starter/generators (S/Gs) is proposed in this study. On the basis of this structure, the control strategy for a single PMSM S/G system is presented, which is suitable for wide-speed operation and high-power application. It can not only achieve both starter and generator functions but also achieve the stability of DC bus voltage. A master–slave current sharing method is derived and can be applied in the HVDC parallel system, compared with the droop-control strategy. The validity of the proposed strategies is verified by simulation studies in a Matlab/Simulation environment.
