变频器再生能量的斩波——逆变回馈

Chopping-Inversion Feedback of Energy Regeneratedby a Frequency Converter

将变频器再生能量回馈到电网中，是降低能源消耗的有效方法。介绍了一种采用单只全控型开关元件与六只半控型开关元件配合使用，组成变频器再生能量回馈电路的方法，并给出了理论分析及实验结果。

Feeding back of energy regenerated by frequency converter to network is an effective method of reducing energy consumption, a method of matting single fully controlled type switching element with six semicontrolled type switching element to form feedback circuit for energy regenerated by frequency converter is introduced, the results of theoretical analysis and test are given as well.
