单相全桥PWM整流器输入电流内环式控制方法的分析与仿真比较

摘要

There are lots of input current inner ring control methods for single-phase full-bridge PWM rectifier. PI and PR control methods are relative mature technologies, but the deadbeat control, repetitive control, adeptive prediction current con-trol and other digital algorithm control are still not mature. In the practical application, the selection of control method might seriously affect the properties of products. The theoretical analysis and simulation comparison for many control methods is car-ried out in this article. It has a certain reference value for practical projects.%单相全桥型PWM整流器的输入电流内环式控制方法多种多样.PI控制、使用虚拟坐标变换的PI控制、PR控制等控制方法技术较成熟,而无差拍电流控制、重复控制、自适应预测电流控制等数字算法控刳尚不成熟.在实际应用中究竟选择何种控制方式,对产品性能影响很大.在此控制方法进行理论分析比较,并利用仿真比较得出一些重要结果,对实际工程有一定的实用参考价值.
