Design and control of a controllable demagnetization module for high-frequency magnet power supplies
摘要
Abstract
At present,the fusion magnet power supply in the form of low voltage and high current mostly adopts the thyristor rectifier scheme.Under the condition of long-term steady-state operation of large current,the magnet power supply in the form of thyristor rectifier will bring large reactive power and energy loss,and the large volume of rectifier transformer leads to low power density and poor flexibility of magnet power supply.In order to effectively improve the power density and working efficiency of the magnet power supply,the high-frequency synchronous rectification scheme using full-controlled devices has been applied to the magnet power supply.Based on the problem that the high-frequency synchronous rectification scheme cannot output negative pressure to meet the needs of magnet demagnetization,a control module composed of IGBT and resist-ance is designed at the output end of the power supply,and the controllable demagnetization of superconducting magnet is realized by cooperating with the magnet converter.Finally,a simulation model is built and a high-frequency power supply prototype is developed for superconducting load test,which verifies the feasibility and effectiveness of the magnet power sup-ply scheme and the control module.关键词
