摘要：
[Background] The high voltage power supply is an important part of the neutral beam injection heating system, which determines the beam energy and the quality of the extraction beam current. With the gradual increase of voltage level, the pulse step modulation (PSM) high voltage power supply cannot meet the experimental requirements. [Purpose] This study aims to design an inverter high voltage power supply based on super capacitor energy storage to achieve fast switching of injected power for neutral beam modulation. [Methods] Super capacitor energy storage was adopted to reduce the required grid capacity and minimize the impact on the grid. The DC-DC resonant converter structure with soft-switching technology was used to improve the response speed of the power supply and reduce the switching loss of the switching devices. After the design of power module circuit topology, system modeling and calculation based on power supply performance specifications, the charging circuit and main loop PSIM simulation model were established, and the power supply performance indexes were simulated and verified. Finally, a test prototype of inverter power supply module was built to conduct the test of relevant performance indexes. [Results and Conclusions] After simulation and experimental verification, the power module is able to achieve a stable output of 1 600 V/50 A, which meets the design requirements of 6 MW/120 kV. © 2024 Science Press.
