方波型电压源逆变器与二阶梯波电压源逆变器的比较研究

摘要

本文报告了对方波型电压源逆变器与二阶梯波电压源逆变器主要参数DF和THD的研究结果.比较研究的结果表明二阶梯波逆变器的输出电源质量明显优于方波逆变器.同时也给出了详尽的计算公式和计算结果.%This paper proposes the results of major parameters such as DF,THD,both in square-waveform voltage source inverters(VSI)and in two-step-level VSIs.Comparison study shows that the quality of two-step-level VSIs is much better than those of square-wave VSI.Detailed calculating formulae and results are presented.
