摘　　要：单/三相变换器一般采用裂相和移相技术,变换效果受负载影响较大,为了平衡变换器的三相输出电压,提高电能质量,结合整流逆变原理,提出一种AVR控制的单/三相变换器,构建硬件拓扑电路,采用SPWM控制方式和双闭环反馈控制策略,利用MATLAB建模仿真并进行实验分析。仿真和实验结果表明,该变换器可以有效克服突变负载的干扰,输出电能质量较高,能在一定程度上提高边远地区三相电源的普及率,满足中小功率三相负载的使用需求。The splitting phase and shifting phase technologies are usually applied in single/three - phase convert- er and the effect of shifting is greatly affected by the load. In order to balance the three -phase output voltage and improve the power quality, based on the principle of rectifier and inverter, a AVR control single / three phase converter was proposed. The hardware topology circuit was built; SPWM control mode and double closed - loop feedback control strategy were adopted. Simulation and experimental analysis were conducted by modeling with MATLAB. The simulation and experimental results showed that the converter can effectively overcome the interference of the mutation load effectively. The good power output quality will improve the popularity rate of the three - phase power supply in remote areas to a certain extent and meet the needs of small and medium power of three phase load.
