摘    要:“跳相”交交变频是在传统交交变频的基础上的扩展,可以将输出频率提高到接近工频频率,且具有无环流、无死区的优点。与单重化交交变频相比,三重化“跳相”交交变频电路具有改变输出电压的能力,相对于现有变频器具有容量大、电压等级高、成本低的优点。以反并联桥电路为基础介绍了“跳相”交交变频的基本思想,以三重化为例,根据电压矢量叠加的方法分析了可能的叠加结果,总结出电压变化的范围,并从中选出三组作为实例,用MATLAB进行了仿真,最后搭建了实验平台,进行了实验分析,实验结果表明理论和仿真分析正确。

关 键 词:交交变频  三重化  矢量叠加  MATLAB

Abstract:"Phase hopping" cycloconverter is an extension based on traditional cycloconverter, which can increase the output frequency to close to the power frequency, and has the advantages of no circulation and no dead zone. Compared with the single-stage cycloconverter, triple-stage cycloconverter have the ability to change the output voltage frequency conversion circuit. Compared with the current inverter it has the advantages of large capacity, high voltage level and low cost. On the basis of the bridge circuit in parallel, we introduced the basic idea of "phase hopping" cycloconverter. With triple-stage cycloconverter as example, according to the voltage vector superposition of superposition method, we analyze the possible results, summarizes the scope of the voltage variation and choose three groups from it as examples. MATLAB was used for simulation. Finally, the experimental platform was set up and the experimental analysis was carried out. The experimental results showed that the theory and simulation analysis were correct.
Keywords:cycloconverters    triple-stage    vector superposition    MATLAB
