【摘要】：为解决单相非隔离光伏并网发电系统中的共模电流问题,近年来大量新型的桥式拓扑被提出。然而,这些拓扑的提出具有随机性,无系统的规律可依据,不利于行业发展。基于单相非隔离光伏并网桥式逆变器,通过分析不同拓扑之间的演化过程,证明了拓扑的相通性,提出了其演化规律。基于提出的演化规律,在现有拓扑基础上推演出一系列新型拓扑,最后通过仿真分析验证了新拓扑的有效性及演化规律的正确性。提出的拓扑相通性及演化规律为更好地理解和研究现有拓扑提供了理论依据,同时也为演化单相非隔离光伏并网桥式逆变器新型拓扑提供了理论参考。
[Abstract]:In order to solve the problem of common mode current single-phase non isolated grid connected photovoltaic power system, a large number of new bridge topology is proposed in recent years. However, the proposed topology is random, no system can be based on the law, is not conducive to the development of the industry. The single-phase transformerless PV Grid connected inverter based on bridge, through the analysis of the evolution between different topology that proves the interlinked topology, puts forward the evolution rules of evolution. Based on the proposed performance push a series of new topology based on the existing topology, simulation results validate the validity of the new topology and evolution. The topological similarities and evolution in order to better understand and study the existing topology provides a theoretical basis, but also for the evolution of new topology and single-phase non isolated photovoltaic inverter bridge to provide a theoretical reference.
