| 摘 要： | 结合高频PWM整流逆变电路高功率因数、低谐波特性,提出了一种可实现再生能量回馈利用的装置。文中介绍了该装置的主电路拓扑结构和工作原理,并根据它的等效电路和功率平衡关系建立了数学模型。从实现单位功率因数有源逆变控制出发,设计了双闭环直接电流控制系统,利用Ziegler-Nichols整定算法得到内外环PI调节器的参数。通过Matlab/Simulink仿真表明,方案设计合理,控制系统有良好的动静态性能。

| Abstract: | Based on high power-factor and low harmonic characteristics of high-frequency PWM rectifier/inverter,an energy feedback equipment is proposed.The main circuit topology and operation principle is introduced,and mathematical model is established by equivalent circuit and power balance.The double closed-loop control system is designed in order to satisfy the unity-power-factor(UPF) condition,and obtain the PI regulator parameters by Ziegler-Nichols method.As a result,good steady and dynamic characteristics of the control system have been shown by Matlab/Simulink simulation. |
