摘　　要：提出了2种具有高电压传输比的新型矩阵变换器,根据逆变侧主电路拓扑结构的不同,将其分别称为Boost矩阵变换器(BMC)和Buck-Boost矩阵变换器(BBMC)。介绍了这2种拓扑结构的基本构成和工作原理,阐述了滑模控制器和双闭环控制器的设计方法,并对其进行了比较,最后通过仿真证明了该新型电路结构的可行性和有效性。结果表明:该电路能实现电压传输比和输出频率的任意调节,且波形失真度小,从而有效地解决了传统矩阵变换器(CMC)电压传输比低的固有缺陷,具有很好的应用价值。This paper presents a novel matrix converter which has high voltage transfer ratio. According to the topology of the inverter side is different, they are called Boost matrix converter （BMC） and Buck-Boost matrix converter （BBMC）.The basic configuration of the new topology and their fundamental principle are firstly introduced, the method of design sliding mode controller and double-loop controller are clarified, analyzed and compared. Finally the validity and feasibility of the new topology are tested by simulation. The results indicate that the regulation of the voltage transfer ratio and output frequency can be realized optionally by the new converter, furthermore the harmonic distortion of waveform is low. So the inherent drawback of low voltage transfer ratio of traditional matrix converter is effectively settled. This study may provide inspiration for further engineering application.
