Optimized design and simulation of a GW-scale Multiphase Air-Core Pulsed Alternator

摘要

Multiphase Air-Core Pulsed Alternators have been studied for almost two decades. However, its design and optimization theories are still rarely reported. The main parameters of this type of alternators have very important influence on the performance. These parameters are often closely associated with system performance parameters, the system structure and the load requirements. This paper begins with describing the basic design theory of the GW-scale air-core pulsed alternator. Then, the relationships of major parameters are analyzed, including the main dimensions, the magnetic field, the armature turns in series per phase, the number of turns per pole of the field winding, the load parameters and etc. Finally, the optimization theories are verified by system-level dynamic simulation.
