In this paper, an asynchronized synchronous motor (ASM) based shipboard power system (SPS) is proposed to achieve cost effective energy regulation for electric ships. Although the widely used power electronics technology contributes to the development of electric ships a lot, the dependency of SPS on power electronic converters keeps increasing. With the application of ASM-based SPS, the overall volume of on-board power electronic devices is greatly reduced. Additionally, the models of three key components, which are the synchronous generator (SG), ASM, and back-to-back (BTB) converter, are established and analyzed. Besides, the transfer function of SG excitation system is obtained, and an ASM control strategy without phase-locked loop (PLL) is proposed to maintain an almost synchronous rotor speed. Furthermore, the simulation study is carried out in Matlab/Simulink to verify the performance of the proposed ASM-based SPS, with frequent load variations taken into consideration.
