Abstract
The cooperative work of multiple modules is an important technical stage in the practical process of inductive pulsed power supply (IPPS). This article proposes a novel configuration of multimodule system, in which the inductors of each module are arranged in a toroidal way. This configuration can greatly improve the energy storage by utilizing the mutual inductance between modules, and the electromagnetic interference can also be reduced. Based on the circuit analysis and formula derivation, the decoupling equivalent greatly simplifies the calculation of system performance. The genetic algorithm (GA) is used for the parametric design of the 2 MJ toroidal IPPS system, and one of the solutions achieves an output current of 361 kA and an energy density of 6.21 MJ/m3. In addition, the three configurations of multimodule IPPS system are compared, and it is found that the proposed toroidal scheme can achieve higher indicators.
