摘要
针对传统交-交变频器功率器件多、控制复杂、功率因数低等缺点,在脉冲阻塞式交-交变频电路控制原理的基础上提出1种输出频率连续的交-交变频电路控制方法.首先给出三相输入三相输出和六相输入三相输出这 2 种交-交变频电路拓扑及其详细的工作原理.然后,搭建MATLAB/Simulink仿真环境下 2 种变频调速系统仿真模型进行仿真实验,仿真结果与理论分析相一致.最后,制作实验样机进行验证,实验结果证明了所提新型变频调速系统控制方法的有效性与可行性.
Abstract
Aimed at the disadvantages of a traditional AC-AC variable frequency converter such as too many power devices,complex control and low power factor,a control method for an AC-AC variable frequency circuit with continuous output frequency based on the plugged pulse AC-AC variable frequency circuit control principle is proposed.The circuit topologies and working principle of a three-phase to three-phase converter and a six-phase to three-phase converter are presented in detail.The simulation models of these two variable frequency speed control systems are established in a MATLAB/Simulink simulation environment,and the simulation results are consistent with the theoretical analysis.Finally,prototypes were fabricated,and the effectiveness and feasibility of the proposed novel control method for variable frequency speed control system were verified by simulation and experimental results.
