Abstract
Pulsed alternator (PA) is a kind of high-power pulsed supplies widely applied in the field of electromagnetic (EM) launch. Over the past decades, the self-excited air-core PA is widely studied, but it has the disadvantages of poor heat transfer and high electric field loss. The hybrid excitation PA combined with the advantages of electric excitation and permanent magnet excitation PA, and the output voltage of armature winding can be adjusted by the electric field current. This paper presents double-electric-excitation hybrid excitation compensated PA (DEE-HECPA). In order to improve the adjustable performance for the output voltage of HECPA, the rotor structure is changed and double excitation coils are used in PA. In this paper, the equivalent magnetic circuit model for hybrid excitation region is established and the air-gap flux density is calculated. The dimensional parameters are calculated by the special EM design method for PA, the characteristics of electric excitation are verified by finite-element analysis, and the characteristics of output current for DEE-HECPA are analyzed. The research results demonstrate that DEE-HECPA is a feasible topology for PA.
