摘要
为抑制非隔离光伏并网逆变系统的地电流,将有源共模噪声抑制器应用于光伏系统。建立了有源共模噪声抑制电路的损耗模型,分析参数及光照变化对损耗的影响,从而提出如何优化设计以减少其损耗对系统效率的影响,最后给出实验验证。
Active Common-noise Canceler (ACC) was proposed to suppress the ground current for grid connected transformerless PV system. The loss analysis was done for ACC. The effect of the parameters and radiation change on loss was studied. The method of optimizing the design was given to reduce the loss and the impact of loss on the system efficiency. The experiment results verify the effectiveness.
