| 摘 要： | 在建立基于理想开关函数的单相四象限变流器数学模型的基础上,对四象限变流器常用的5种控制策略进行研究,并通过计算机仿真对各种控制策略的控制性能进行对比分析。仿真结果表明,预测电流控制和瞬态电流控制可以达到直流侧电压稳定、网侧电流谐波小、网侧单位功率因数等控制目标。

| Abstract: | Based on the mathematic model of ideal switch function for a single-phase 4-quadrant converter, five kinds of control strategy are studied, and analysis is made for each strategy by computer simulation. Results show that the predicted current control and transient current control can reach the control aims, such as voltage stabilization of DC-link,low harmonic distortion of the line current and unity power factor. |
