| 摘要: |
| 太阳能电池板使用旁路二极管避免阴影效应和热斑，二极管的内阻会损耗电流。提出采用一种名为智能重构旁路二极管的新型二极管布局，通过智能判断并短路未使用的旁路二极管，来增加局部被遮挡太阳能电池板的输出功率。文中阐明了智能重构二极管的实现原理，建立了电路模型。提出通过太阳能电池片电压的大小，判断控制二极管拓扑结构的开关状态的判定规则。进行了模拟仿真，实验验证了仿真结果。基于实验结果，并与普通二极管布局对比，采用智能重构二极管布局的太阳能电池板输出功率提升可达到12.24%。 |

| Abstract: |
| Solar panel uses bypass diodes to avoid shading effect and hot spot. Currently the power produced by the solar panel suffers from wasting current by bypass diodes. In this paper a new diode structure called Smart-diode is proposed to increase the output power of a solar panel in partial shading by shorting out resistance from unused bypass didoes. The principle of Smart-diode is explained, and the circuit model is built. The theory of controlling switches for bypass diodes by voltage of solar cells is analyzed. The simulation model is simulated and verified by the experiment. Based on our experiment result, comparing with the normal structure of diodes, power of a solar panel can be improved up to 12.24% with Smart-Diode structure. |
