摘要: | 本研究旨在設計一熱電半導體發電系統,利用迴路熱管(LHP)被動式散熱技術,降低熱電半導體發電系統冷端溫度,以提升溫差達到增加發電量的目的。
本研究同探討熱電半導體發電系統的最大功率點追蹤控制器,以維持熱電半導體發電系統之最大功率輸出。最後進行熱電半導體發電系統近最大功率點操作(nMPPO)設計研究。由本研究測試結果可知,只要熱電半導體發電系統的熱端溫度在150℃~210℃內,其nMPPO轉換效率可高於MPPT轉換效率。 最後分析MPPT與nMPPO的適用性,在MPPT部分,當熱端溫度範圍大於 150℃~210℃時適用,且MPPT不受系統老化影響,可長時間使用;而nMPPO部分,適用於熱端溫度為150℃~210℃,且使用時間較短。 This thesis aims to design-ThermoElectric Generator System. The ThermoElectric Generator System generates power by temperature difference. The hot side uses a heater to simulate exhaust heat. The cooling side is particularly designed utilizing the passive heat sink tech, Loop Heat Pipe. As a result, the system achieves the goal of electricity generation. The study discusses the Maximum Power Point Trick controller in order to maintain the maximum power exportation. Then, the final step is about to research the design of ThermoElectric Generator System with near Maximum Power Point Operation (nMPPO), According to testing result of the study, As long as the temperature of hot side of ThermoElectric Generator System(TEGS) stays within 150℃~210℃, the transformative efficiency of nMPPO will higher than the one of MPPT. Finally, the study analyses the proper usage of the MPPT and the nMPPO. First, the usage of MPPT is suitable for using when the temperature range of hot side is higher than 150℃~210℃. In addition, the MPPT is not affected by systematic ageing effect. It can be used for a long time. Second, the usage of nMPPO is suitably used when the hot side is within 150℃~210℃. Moreover, the time which it is able to be used is much shorter. |
