摘要
矩阵变换器(MC)在实际工作时存在一定的谐波,对所带的负载将产生很大的影响。基于矩阵变换器(MC)空间矢量调制法,提出了一种优化的阻尼输入滤波器。从输入侧将矩阵变换器功率单元等效电流源,推导出了输入滤波器稳态时数学表达式,得到了并联在电容两端电阻的计算公式,通过静态寻优法,确定了适合系统的最优值。在Matlab/Simullink中进行了建模和仿真,结果验证了分析结果的可行性。
In practical work there are a large number of harmonic in matrix converter ,which will produce a bigeffect to load. Based on the space vector modulation strategy of matrix converter,a optimized damped input filter wasproposed.Looking from input side of matrix converter,the power unit of MC is equivalented a current source,inputfilter steady-state mathematical expressions was deduced,and gain the calculation formula of the resistance. Fromthe static optimization method,determined the optimal value of the resistance. To vertify the conclusion,the modelingand simulink of matrix converter are built in Matlab/Simulink. The simulation results confirm the feasibility of thismethod.
