| 为提高矩阵变换器的电压传输比，加速其在电力传动领域的应用，在矩阵整流和交流斩波器的基础上提出了一种新颖的交直交型Sepic 矩阵变换器。首先介绍单相Sepic逆变器的拓扑结构和工作原理，在此基础上进一步介绍基于矩阵整理和交流斩波的Sepic矩阵变换器的拓扑结构，然后分别阐述整流级和逆变级所采用的调制策略，最后通过仿真和样机试验证明该拓扑结构的正确性及调制策略的可行性。仿真和样机试验结果表明该系统的电压传输比能够达到1.0及以上，从而突破了传统矩阵变换器电压传输比最大为0.866的限制，且系统输出电压和电流波形的失真度很小，因此具有较好的研究价值。 |

| In order to improve the voltage transfer ratio of matrix converter and accelerate its application in the field of power transmission, a novel AC DC AC Sepic matrix converter based on matrix rectification and AC chopper is presented in this paper. Firstly, the topology and working principle of Sepic inverter is introduced. Based on the above analysis, the topology of Sepic matrix converter is also introduced. Then, the modulation strategy used in rectifier stage and inverter stage is expounded. Finally, the correctness of the topology and the feasibility of the modulation strategy are proved by simulation and prototype experiments. The simulation and prototype test results show that the voltage transmission of this system can reach 1 and above, which breaks through the traditional voltage transfer ratio of matrix converter 0.866 maximum limit, and the system output voltage and current waveform distortion is very small, so it has good value of research. |
