通过对高功率因数变流器网侧指令和实际电流的预测 ,提出了一种采用变流器电压矢量优化控制策略的电流跟踪新方案。新方案根据电流偏差的大小 ,采用不同的电压矢量控制模式 ,使变流器网侧电流获得了较快的动态响应 ,同时也抑制了谐波电流。

This paper discusses a new control tactics of the converter which adopt voltage vector optimum control tactics by predicting the current of high power factor converter. As a result of taking different voltage vector control pattern according to the range of current deviation, the appropriate converter possesses more quick dynamic response and eliminates harmonic current component.
