Abstract

As power supplies, compulsators are popular choices for electromagnetic railguns. Compared to a single-phase system, multiphase compulsator can provide more flexibility in current waveform and higher power density. However, the accurate simulation method of a multiphase compulsator is still not clear enough for researchers since both the machine and the external circuit become more complex. With this background in mind, this paper describes a finite-element method combined with circuit analysis. The compulsator is modeled in Maxwell while the railgun launcher and external circuits are modeled in Simplorer, each with their respective advantages. Based on this model, the performances of the two-and three-phase air-core compulsator powered railgun systems are analyzed. The compensation modes, trigger control, and output characteristics are also discussed. The co-simulation model and analysis results can provide the theoretical guides for multiphase compulsator investigation in the future.
