The repetitive pulsed magnetic field (RPMF) is a common type of microwave guided magnetic field, which is used to constrain and limit the electron beam in high power microwave (HPM) devices. However, when using RPMF, the limitations of charging time, charging power and eddy current effect pose significant challenges to improving the repetitive frequency and magnetic field intensity. To address this issue, a novel RPMF system is proposed in this paper. First, the simulated annealing genetic algorithm is employed to optimize the parameters of the RPMF system. Based on these optimizations, a low-loss circuit topology is proposed, which effectively enhances the repetitive frequency and magnetic field intensity of the RPMF. Furthermore, an experimental prototype of the RPMF system is fabricated. The results demonstrate that the whole system can generate a 3.5 T/30 Hz RPMF in a magnet with a radius of 48 mm, with a magnetic field uniformity of 95.93% over a 100 mm uniform region. Finally, the system's charging power is 26.27 kW, validating the effectiveness and feasibility of this design.
