摘要

本文提出了一种新型的单相交-直-交五电平x型电流源变换器。x型拓扑的使用降低了变换器的导通损耗,而五电平配置可以降低较低频率下的总谐波畸变,并允许增加变换器的功率能力。本文的新颖之处在于将多电平配置应用于x型电流源变换器。介绍了该变换器的工作原理和正弦三角形脉宽调制,并通过仿真结果进行了验证。此外,还给出了整流侧(交直流)的实验结果。

Single-Phase AC-DC-AC Five-level X-type Current Source Converter
In this paper a new single-phase AC-DC-AC five- level X-type current source converter is proposed. The use of the X-type topology reduces the conduction losses of the converter, whilst the five-level configuration may reduce the total harmonic distortion under lower frequencies, and allows the increase of the power capability of the converter. The novelty of this paper resides on the multilevel configuration being applied to a X-type current source converter. The operation and sine- triangle pulse-width modulation of the proposed converter are presented, as they are validated by simulation results. Besides that, experimental results for the rectifier side (AC-DC) are presented.
