Abstract

The application of a multiphase air-core pulsed alternator (APA) power supply system in railgun has been studied. First, the working principle of the multiphase APA power supply system driving the railgun is introduced in detail, and the mathematical models of the multiphase APA and the railgun are given. Second, the discharge characteristics of the multiphase APA power supply system are analyzed. The relationship between the load current and the phase current is expounded at the theoretical level, and the characteristics such as the amplitude and pulsewidth of the phase current during the discharge process of the eight-phase motor are analyzed and parsed. Then, a field-circuit coupling simulation model is constructed to simulate and analyze the discharge process of the multiphase APA driving the railgun, verifying the correctness of the theoretical analysis. Finally, the experimental platform of multiphase APA driving the railgun is built, and the launch experiments are successfully conducted. Meanwhile, valuable experimental data are also provided for the subsequent further experiments.
