摘要

无变压器光伏发电系统具有成本低、体积小、效率高等优点，具有广阔的应用前景。其最重要的问题之一是如何防止共模漏电流。为了解决这一问题，本文提出了一种新型逆变器。建立了系统共模模型，分析了逆变器的四种工作模式。结果表明，共模电压可以保持恒定，从而可以抑制泄漏电流。最后进行了实验测试。实验结果验证了该方法的有效性。

A Novel Inverter Topology for Single-Phase Transformerless PV System

Transformerless photovoltaic (PV) power system is very promising due to its low cost, small size, and high efficiency. One of its most important issues is how to prevent the common mode leakage current. In order to solve the problem, a new inverter is proposed in this paper. The system common mode model is established, and the four operation modes of the inverter are analyzed. It reveals that the common mode voltage can be kept constant, and consequently the leakage current can be suppressed. Finally, the experimental tests are conducted. The experimental results verify the effectiveness of the proposed solution.
