| 摘 要： | 建立了三相电压型并网逆变器数学模型,在此基础上提出了一种基于滑模变结构的三相电压型并网逆变器直接功率控制策略,详细论述了控制策略原理及设计过程.该控制策略将滑模变结构控制器、直接功率控制和空间矢量脉宽调制技术相结合,不需要同步速旋转坐标变换即可实现恒定的开关频率,具有良好的稳态性能和快速的动态特性.在一台3 kVA的并网逆变器样机上进行了实验研究,结果证明了所提出的滑模变结构直接功率控制策略的正确性和有效性.

| Abstract: | The mathematical model of the three-phase grid-connected voltage source inverter (GC-VSI) is developed. Based on the model,a novel sliding mode variable structure(SMVS) based direct power control (DPC) strategy is proposed for the three-phase GC-VSI. The principle and design scheme of the proposed SMVS-DPC strategy is studied in detail. The proposed SMVS-DPC strategy combines SMVS controller,DPC method and space vector pulse width modulation (SVPWM) technique together to implement a constant switching frequ... |
