本文提出了一种新颖的旁路方法，用于依靠饱和运行的双极晶体管的光伏电池板，其激活由仅包含一对 MOS 晶体管的电路自动处理。解释了所提出系统的工作原理，并量化了与传统的基于二极管的方案相比，旁路子面板的可靠性和串产生的功率方面的改进。该分析通过直流/瞬态测量和定制的 PSPICE 仿真得到证实。
This paper presents a novel bypass approach for photovoltaic panels relying on a bipolar transistor operated in saturation, the activation of which is handled automatically by a circuit comprising a pair of MOS transistors only. The functioning principle of the proposed system is explained and the improvements in terms of reliability of the bypassed subpanel and power produced by the string in comparison with a traditional diode-based scheme are quantified. The analysis is corroborated by dc/transient measurements and tailored PSPICE simulations.
