逆變器基準信號幾種產生方法的研究

摘要：部分數字化控制逆變器中的基準正弦信號由微處理器產生。本文研究分析了正弦波的幾種數字化產生方法，以及數值和時間量化對基準信號諧波含量的影響，并給出了實驗結果。 敘詞：逆變器，數字控制，諧波分析 Abstract： In some digitized control inverters, the reference sine signal are generated by Microprocessor. This paper analyses some kinds of digitized generation methods of sine wave and the influence of the quantization of the value and time on the reference signal’ THD. The experimental results are given to verify the effectiveness of the proposed methods at the end of this paper. Keyword：inverter, digital control, THD analysis
