摘　　要：因为变频调速电梯在运行时,变频器输出存在量谐波,介绍了一种新型的功率变换器,引入了电压电流双闭环控制策略,分析了一种新型的矩阵变换器输出电压和电流的谐波成分及影响因素,通过MATLAB/SIMULINK软件进行了仿真试验,结果表明,与传统的变频器相比,矩阵变换器结合输出电压电流双闭环控制,能够有效地降低输出电压电流谐波,并能抑制输入侧谐波对输出电压电流的影响。The harmonic components is caused by the output of voltage and current of VVVF, which greatly impacts on the load. Aiming to solve the problem, the voltage current dual-loop control strategy of a novel matrix converter is introduced. The voltage and current harmonics are analyzed, which overcomes the obstacles of troditional converter, such as lager bulk capacitor and inductor. The voltage current dual-loop control system is presented. The simulation results show that the novel matrix is effective in eliminating harmonics of matrix converter, which has better performance than contraditional converter and can overcome the influence of the grid harmonic disturbance.
