磁通泵是给超导磁体供电的装置，本文主要介绍磁通泵的国内外发展情况，论述磁通泵的运行原理，计算磁通泵的运行参数和运行损耗。

英文摘要：

Superconductivity has been found for more than ninety years. The application of superconductivity is more and more, especially superconducting magnet. But, we must slove the problem of power supply for superconducting magnet before the application. Usually, current lead is used for supplying power for superconducting magnet. While, flux pump is another choice, which is also named superconducting rectifier. At first, the article introduces current lead and flux pump, especially the progress of flux pump in recent years, following explains the stucture and principle of flux pump, finally calculates the moving paremeter of flux pump. Then, enumerates the conclusions are enumerated.
