| 中文摘要 | 对单相无隔离变压器光伏并网系统共模电流的产生机理进行简要分析,并对单相全桥拓扑的两种控制方式分别进行仿真。同时对多种能够消除共模电流的单相无隔离变压器光伏并网系统的拓扑进行分析与仿真。从拓扑器件数量、控制复杂程度、功率损耗、滤波效果、系统共模电流5个方面比较各种拓扑的优劣,最后,分析结果表明,H5拓扑结构最优,适合未来实际发展与推广。; Briefly analyzed the mechanism of common mode current generation for the single phase transformerless photovoltaic(PV)grid system and simulated the two kinds of control methods of single phase full bridge topology. Analyzed and simulated lots of transformerless single-phase PV inverter topologies and these topologies can eliminate the common mode current. They were compared in device number,control complexity,power loss,filtering effect,the common mode current. Finally,the analysis results show that H5 topology is optimal,suitable for the actual development and promotion. |
