減少環境污染與使用潔淨能源為政府當前之重要施政方針。國科會海工學門亦在先進節能船舶技術中，明訂太陽能等綠色能源的利用為研究重點。本研究之目的在改善現有太陽光電池之最大功率追縱控制設計，發展出單變數電流法，以改善傳統擾動法之缺點，並求提高太陽能電力使用之功率。研究中使用國家儀器公司之Compact RIO模組，此模組運用LabView 程式燒入FPGA晶片，使得開發之運算法得以達到穩定、高效率的整合型系統；並與自行製作降壓電路；以調整功率開關導通時間進而控制輸出，以達到最大功率要求；且由模擬與實測結果以驗證本文所提系統之可行性。

Reduction of environmental pollution and the use of clean energy resource are part of the major concerns of the government mandates. To cope with the policies, the Ocean Engineering Division of NSC has regulated its Advanced Energy-Saved Naval Technology guidelines, and the use of green energy, such as solar energy, is one of the major subjects. This study tries to improve the Maximum Power Point Tracker (MPPT) control algorithm of solar cell, and proposes the modified perturbation and observation method for MPPT control in order to increase the efficiency of solar power usage. By integrating the FPGA chip and compact real-time I/O modules (cRIO) of National Instrument, self-designed power switch voltage reduction buck DC/DC converter circuitries, a real performance experiment will be carried out to demonstrate the performance of the proposed energy saving algorithm.
