基于Buck电路的矩阵式变换器
资料介绍
通过分析直流降压斩波（DC／DCBuck）的工作原理，推导出一种新颖的针对矩阵式变换器的控制策略。该控制策略相对于Venturini直接函数变换法和空间矢量调制法其优点在于：只须简单的数值（电流或电压）大小的比较，而不需要复杂的数学运算。并且该策略编程简单，控制方法和工作过程容易实现，具有很高的时效性。通过对其产生的谐波分析。得出主要的谐波是开关频率附近的高次谐波，有利于滤波。本策略采用电流滞环控制方式，所以其开关动作响应快。具有一定的抗干扰性。最后通过Matlab中的Simulink仿真．仿真结果证明了该控制策略理论分析的正确性和可行性。
The principle based on the DC step-down chopper （DC/DC Buck） was described in detail, and a novel matrix converter strategy was derived. Comparing with the Venturini direct function transformation method and space vector modulation method, the advantages of the strategy are that it is a simple comparison of numerical values （current or voltage）,but not a complex mathematical operation; the programming approach of the strategy is simple, and the control method and working process can easily be realized with high time effectiveness. By analyzing the harmonic, it is concluded that the main harmonic are high order harmonic component around the switching frequency, which i...
