摘 要: 通过对矩阵式变换器中双向开关的逻辑控制,可变换其电压和频率。据输入非平衡、输出平衡时矩阵变换器的工作原理,用Matlab建立输入非平衡时矩阵变换器的输入电流偏置角动态调制策略(SVM算法)的仿真模型。该模型由三相非平衡电源、矩阵开关、三相负载和电压表、电流表、示波器等模块和控制策略等构成。 The bio-switches of the matrix converter were controlled logistically can transform the voltage and frequency of matrix converter. According to the principles of the matrix converter while working in unbalance input and balance input condition, the simulation model for dynamic modulation strategy of offset angle of input current for matrix converter was founded with Matlab in unbalance input. The model is made of unbalance 3-phase electrical soure, matrix converter switch, 3-phase load, voltage meter, current meter, oscillograph and the modulation strategy.
