UPS电源输出变压器的偏磁分析

The Analysis of Magnet Bias for the Output Transformer in the UPS

本文讨论了UPS电源的重要组成部分变压器的偏磁问题。深入分析了变压器产生偏磁的根本原因及主要因素,在此基础上提出了全数字PI控制,并通过实验验证了该方法的可行性和有效性。

In this paper, the magnet bias problem of the UPS output transformer is analyzed. The magnet bias is very important to the quality of the UPS, and it can improve the whole DC-AC system of the power source. In order to solve the transformers magnet bias, the radical reasons and primary factors are discussed in depth. Therefore, the whole digital PI control method is brought forward. The method is proved to be effective by experiment.
