中文摘要 | 本文電能管理的研究分為發電系統及照明系統兩部分。在發電系統部份,充電電路採用零電壓切換式直流/直流轉換器並搭配最大功率追蹤控制技術,以提升太陽能的發電及充電電路的效率。在照明系統部分,本文提出區段調光曲線,作為電能管理的設計方法,調光曲線的設計則根據人類夜間的作息習慣,並藉由偵測蓄電池電壓的大小,以決定冷陰極燈管於各調光區段之輸出功率,進而達到節能及持續照明之目的。由區段調光的實驗結果顯示,當蓄電池電壓為24.4 V、25.4 V時,點燈電路的平均效率約91.5%、91.2%,節能百分比約15.3%、23.6%。本文所設計的太陽能照明調光系統,具高效率、節能、持續照明的功能,符合綠色照明之實用潮流。 |
英文摘要 | The object of this study comprises an electricity generation system and a lighting system. The charging circuit adopts a zero-voltage-switching (ZVS) DC/DC converter along with the maximum-power point tracking (MPPT) control technique to enhance the solar energy's electricity generation and the charging circuit's conversion efficiency. In the lighting system, we propose a time-zone-wise dimming curve, based on people's evening activity habits, to provide guidelines for a night lighting management; we also detect battery voltage magnitude to determine each cold-cathode fluorescent lamp's (CCFL) output power in each dimming time-zone, to reach the purpose of energy conservation and continuous lighting. The experimental results from said time-zoned dimming indicate that when the battery voltage is 24.4 V and 25.4 V, the average efficiency of the lamp-ignition circuit is approximately 91.5% and 91.2%, respectively, and the energy-conservation percentage ratio is approximately 15.3% and 23.6%, respectively. The solar-powered dimming system proposed and designed herein can meet the requirements of high power conversion efficiency, energy conservation and continuous lighting for the current trend of green lighting. |
