直流电源的反馈试验法的研究

本文介绍了比传统方法更为经济、高效的直流电源反馈试验法，提出了电能回馈方法。首先对比了新老试验方法不同，然后介绍了实现方案，详述了基准正弦生成电路和DC／AC部分的组成及其原理。最后进行了理论分析和仿真验证，证明该方案符合技术要求。

Research on converter-loading back test in DC power supply

The present paper recommends a power-back test in DC power supply which performs low cost and high efficiency in contrast to tradition, and proposes a power-return project, For one thing, differences come up between new and old methods. Afterwards, the thesis exhibits how to realize the project, and expounds basic sine-wave circuit and the structure and principle of DC/AC, especially. The results of theory analysis and simulate are given, and conclude that the project could satisfy technology need.
