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

Analysis and Simulation of Inner Ring Control Method of Supply Current Applied in Single-Phase Full Bridge PWM Rectifier

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为成熟,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制则尚不成熟。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。本文首先对多种控制方法进行理论分析比较,然后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。

There are lots of inner ring control methods of supply current applied in single - phase PWM rectifier. PI or PR control method, and so on are relative mature technology, but deadbeat control and repetitive control, etc are tentative technology. Which control method to be chosen in practical application will seriously affect properties of products. So analysis and simulation are carryied out in this article, and it has a certain reference value for practical project.
