Abstract
En 中文
In the research of pulsed power supplies (PPSs) for electromagnetic launch (EML), it is of great significance to improve the energy density and waveform modulation capability. This article proposes an asynchronous multimodule coupled inductive PPS (IPPS) system and a rapid analysis method for it, which has a higher energy density than that of the planar IPPS system, and meanwhile, it has a more flexible spatial structure and sufficient waveform modulation capabilities. In view of the high complexity of the system circuit, the symmetric equivalent method (SEM) is proposed. By combining it with the homogeneous circuit order reduction method (HCORM), the solution of the multimodule circuit is simplified into the solutions of multiple low-order circuits, which greatly improves the calculation speed. An example is selected, and the system and method are verified by MATLAB/Simulink simulation. The calculation speed of this method is about 27.9 times that of the simulation, and the root-mean-squared error (RMSE) is extremely small. Besides, its energy density can be 106.8% higher than that of the planar system. This research provides theoretical support and methodological references for the future optimized design, operation, and practical application of IPPS systems.
