[[abstract]]本篇論文中，提出一再生能源採集器之智慧型積體電路(IC)和系統設計。在這個設計中，一個8位元的微控制器被使用在偵測和轉換太陽能電池模組、風力發電機和電池的輸出電壓和電流值。這些輸出值在被微控制器計算然後開發出最大功率追蹤演算法與充電演算法。然後再設計出一個智慧型充電IC，它是遵循著微控制器輸出指令去控制太陽能電池模組或風力發電機操作在最大功率點，並且也在本文所提出的電源轉換器下去有效的控制電池充電在最佳模式下。 所提出的IC在與微控制器結合實現出再生能源採集器。透過微控制器的RS232可以將太陽能電池模組、風力發電機、能量採集和電池的操作資訊轉移至筆記型電腦上，因此所提出的設計和管理工具能夠診斷目前系統的操作情況並且做出適當的維護決策。 本論文已完成智慧型充電脈波寬度調變器晶片設計。電路設計中加入溫度補償設計，使類比積體電路操作在溫度變化劇烈的環境中，依舊能保持原電路之優異特性，增加系統的電壓穩定度，減少無謂的功率損失。這些晶片皆循國家晶片設計中心下線流程，並使用台灣積體電路製造股份有限公司所提供的0.35μm 2P4M 3.3V/5V mixed-signal process製作。智慧型充電脈波寬度調變器晶片面積為0.98*0.98mm2，與一般充電IC比較起來面積縮小許多。[[abstract]]In this thesis, a smart integrated circuit (IC) and system is proposed for renewable energy harvester designs. In this design, an 8-bit microcontroller chip is used to sense and transform the voltages and currents of a solar panel, a wind turbine, and a battery into digital output values. These output values are calculated in the microcontroller chip to build the maximum power point tracking and charging algorithm. A smart charger IC is then designed to follow the microcontroller’s output command to control the solar panel or the wind turbine at the maximum power point, and also to charge the battery at an effective mode with the proposed power converter. The proposed IC is then combined with the microcontroller chip to implement the renewable energy harvester. The operating information of the solar panel, wind turbine, energy harvester, and the battery will be transferred to a notebook computer through the RS232 interface of the microcontroller chip, so that the proposed design and management tool can judge the system's operating conditions and make appropriate maintenance decisions. Two chips are finished in this thesis. All of the chips had been taped out through the design flow of the Chip Implementation Center (CIC). Then, the chips are fabricated with TSMC 0.35μm 2P4M 3.3V/5V mixed-signal process. These chips are smart charge pulse-width modulator (SCPWM) IC, P-V charge pulse-width modulator (PCPWM) IC, respectively. The chip area of SCPWM is about 0.98*0.98 mm2. The chip area of PCPWM is about 0.98*0.98 mm2
