摘　　要：为了提高电力系统的可靠性、效率和质量,提出基于矩阵运算的电力变换器性能优化研究。借助数学矩阵理论,将输入矩阵转换为输出矩阵,使用矩阵乘法来实现三相输入变换器电流和电压的变频,并产生三相输出电流和电压。采用分立式开关器件使开关达到双向功能,利用四步换流法改变电流方向,通过直接传递函数调制策略,确保矩阵式变换器的安全运行。实验结果表明,该方法不仅可以显著提高输出电流的功率,而且能够增大变频范围,从而提高传输效率。In order to improve the reliability,efficiency and quality of power system,the optimization of power converter performance based on matrix operation is proposed.With the help of mathematical matrix theory,the input matrix is converted into the output matrix,and the current and voltage of the three-phase input converter are converted by matrix multiplication,and the three-phase output current and voltage are generated.The switch can achieve bidirectional function by using separate switching device,the current direction is changed by four-step commutation method,and the safe operation of matrix converter is ensured by direct transfer function modulation strategy.The experimental results show that this method can not only significantly increase the output current power,but also increase the frequency conversion range,so as to improve the transmission efficiency.
