中频变压器空心铜绕组交流损耗的全解析模型

Hollow copper windings used in medium-frequency transformers can not only reduce losses, but also improve heat dissipation efficiency by passing coolant through the center of the conductor. In this article, the high-frequency ac loss of the hollow copper winding of the transformer is modeled. By decomposing the rectangular hollow copper winding with complex structure into three parallel solid copp...
