Dynamic loss is significant for evaluating the performance of type-II high-temperature superconductor (HTS) coated conductors (CC), especially when used in electric machines. Although analytical expressions of dynamic loss have been proposed and verified for HTS CCs exposed to low external magnetic fields with a low current load rate, the non-linearity of dynamic loss at high current load ratios and simultaneous high magnetic fields is still unclear and cannot be predicted by the existing analytical equations. This paper proposes a completely new formulation to characterize the non-linearity of dynamic loss taking into account the J c ( B ) dependence of CCs, which can be used for full ranges of both magnetic fields and current load ratios. The proposed analytical formulas have been verified by a T -formulation based numerical model and experiments. This paper comprehensively demonstrates the variation of dynamic loss and provides a meaningfu...

用于高温超导体涂层导体动态损耗的全范围配方

动态损耗对于评估II型高温超导体（HTS）涂层导体（CC）的性能非常重要，尤其是在电机中使用时。尽管已经提出并验证了在低电流负载率下暴露于低外部磁场的HTS CC的动态损耗的解析表达式，但在高电流负载比和同时存在高磁场的情况下动态损耗的非线性仍然不清楚，无法解决。由现有的解析方程预测。本文提出了一种全新的公式来描述动态损耗的非线性，同时考虑了CC的J c（B）依赖性，该公式可用于磁场和电流负载比的全部范围。所提出的解析公式已通过基于T公式的数值模型和实验进行了验证。本文全面论证了动态损耗的变化，并提供了有意义的意义。
