摘要

高温超导（HTS）磁体工作在持续电流模式下，会受到电流衰减的影响。固态电源和多ka电流引线的占地面积和能量需求对聚变装置的尺寸和效率造成了重大限制。变压器-整流磁通泵作为一种新的供电方式，消除了传统电流引线引起的热泄漏，提供了较高的效率。本文介绍了一种用于高温超导磁体供电和维护的10ka变压器-整流磁通泵的新型电磁设计和结构设计。磁通泵由铁芯变压器供电，铁芯变压器具有铜初级绕组和高温超导次级绕组。$J_{\ mathm {c}B}$开关用作整流器，对磁体充电。通过仿真验证了该原理，并根据仿真结果进行了相应的机械结构设计。

The Electromagnetic and Structural Design of a 10 kA-Class Full-Wave HTS Transformer-Rectifier

High-temperature superconducting (HTS) magnets operating in persistent current mode suffer from current decay. The footprint and energy requirements of a solid-state power supply and multi-kA current leads impose significant constraints on the size and efficiency of a fusion device. The transformer-rectifier flux pump is emerging as a novel method of supplying current, which eliminates heat leakage caused by traditional current leads and offers relatively high efficiency. In this paper, we introduce a new electromagnetic design and structural design for a 10 kA transformer-rectifier flux pump to power and maintain HTS magnets. The flux pump is powered by an iron-core transformer, which has a copper primary winding and a HTS secondary winding.

$J_{\mathrm{c}B}$

switch is used as a rectifier to charge the magnet. The principle is validated through simulation, and the corresponding mechanical structure design is conducted based on the simulation results.
