摘要
研究了一种单级双向Buck-Boost逆变器的工作原理,针对此逆变拓扑,应用了归一化峰值纹波控制方法。对归一化算法进行了分析与说明,将归一化峰值控制方法与传统的电压电流双环控制方法进行对比,并利用PSCAD平台对归一化峰值控制方法进行了仿真实验,实验结果证明该方法能很好地减小输出电压的峰值纹波。
Working principles of a single-stage bidirectional Buck-Boost inverter was studied in this paper. The normalized peak ripple control methods was applied for this inverter topology. The normalization algo- rithm was also analyzed and illustrated in details. And the normalized peak voltage control method was compared with the traditional method of the current loop control. The simulation experiment was conduc ted by using PSCAD platform. The results of normalized peak method for controlling shows that this method can reduce the peak output voltage ripple.
