摘要:
详细地分析了无变压器光伏并网系统的共模电流产生机理。用不同的控制方法分析了单相无变压器全桥拓扑结构的共模电流,并对一种新的拓扑结构进行了分析和仿真研究;同时介绍了几种不同的三相无变压器拓扑结构,并作了简单的分析和仿真。最后分别比较了单相和三相无变压器光伏并网逆变器拓扑结构的不同。
Abstract:
It is analyzed detailedly the mechanism of common mode current for the transformerless photovoltaic inverter system. Different control methods are used to analyze the common mode current of single-phase transformerless full-bridge topology, and a new topology is also analyzed and simulated. It introduces several different three-phase transformerless topologies, and makes a simple analysis and simulation. Finally, the differences of single-phase and three-phase transformerless photovoltaic inverter topologies are compared.
