傳統太陽電池供電系統，一般均以獨立供電系統的型態居多，且均附帶有
蓄電池等儲能設備，藉以儲存電能，以作為陰雨天等天候不良時的電力供
應；本研究係針對太陽電池供電系統，研究一種新的控制方式，使其所產
生之電能可與市電直接並聯，藉以省略儲能設備，並解決部分尖峰電力不
足問題。文中除就太陽電池供電系統、升壓式轉換器、反流器及控制電路
等相關技術，作了簡單的概述外，並實際利用87C196MC單晶片控制方式，
直接控制一個約240W之多晶矽太陽電池供電系統，使其所生產之電能可與
市電直接並聯，實驗證明了本控制器的可行性。

The conventional photovoltaic power system are mostly stand-
alone types, which accompanied with power storage systems in
accommodation with the cloudy weather. This study is to find a
new strategy, in which the photovoltaic power can be directly
connected with utility grid, in order to remove the power
storage systems and solve the peak-time power shortage problem.
This paper introduces the operation principles about the
related technologies of the photovoltaic power system, the
boost converter, the inverter and the control strategy. In this
paper, moreover, it also practically utilizes 87C196MC single
chips to control a 240 W poly-crystal grid-connected
photovoltaic power system. Experiment shows that the
feasibility of the controller has been proven.
