| 摘 要： | 对三相双降压式并网逆变器这一新型拓扑的滑模控制进行了研究,使系统获得良好的鲁棒性。首先,对三相双降压式并网逆变器进行了等效分析。然后,根据等效分析电路重点对其滑模控制进行了设计,并在控制律中采用了平滑函数来取代符号函数以削弱抖振。仿真结果表明,采用滑模控制后的三相双降压式并网逆变器具有很好的动态和稳态性能,且输出的并网电流谐波含量低,波形质量好。 |

| Abstract: | To obtain the good robustness,sliding mode control of the three-phase dual buck grid-connected inverter is studied.Firstly,the control system can be designed based on the equivalent analysis circuit.Then,its sliding mode control is designed based on the equivalent analysis circuit.And the sign function of control rate is replaced by the smooth function to weaken the chattering.Simulation results show that the inverter used sliding mode control show good dynamic and static performance.And the output current of the inverter is high quality and the harmonic content is low. |
| Keywords: | three-phase dual buck grid-connected inverter bridge arm through sliding mode control equivalent control robustness |
