Abstract:	高聚光型太陽能系統為目前發電產值最高的系統，利用聚光模組將大範圍的陽光聚焦，並照射在太陽能電池上，如此可縮小太陽能電池面積，降低發電成本。但若要提高最大發電效率，必須要降低追日的偏差角度。本文以軌跡公式混合短路電流之研究為基礎，可使機構老化、機構誤差以及定位誤差等問題不影響追日準確性。並發展量產化之電路板於高聚光型太陽能系統實現，比起市面上常見的追日控制器：主動式光感測器裝日與被動式軌跡追日，能夠有效降低控制器成本。另配合提出的方位角校正策略，簡化原本軌跡公式追日之校正步驟，仰角則提出使用角度與脈波數關係得到回歸曲線，可更有利於機台的量產化與校正，並可適用於不同的機構設計，以得到最佳輸出功率。;HCPV system is currently the highest power output of the system, the use of large-scale concentrator module focus sunlight and exposure on the solar cell. It could reduce the area of solar cells and reduce the cost of electricity. However, to increase the maximum power generation efficiency, we must reduce the deviation angle. This study is based on short-circuit current disturbance mixed trajectory tracking method. Enables organizations to aging, body positioning error and other issues do not affect the accuracy. Designing the mass productive solar board can reduce controller cost to HCPV system. Compared to the common controller : active controller with light sensor and Passive formula tracker controller, it can effect to reduce controller cost. In addition, this study propose a strategy with azimuth correction. It help the correct step become easier. Elevation is proposed to use the number of relations with the pulse regression curve. The amount may be more conducive to the production of machines and Correction. It’s suitable for different mechanism design, and get the best output power.
