指導教授 : 呂文隆

摘要


本論文旨在量測返馳式轉換器、功率因數修正器、升壓降壓轉換器實際波形及使用模擬軟體分析三種電路架構及太陽光電發電系統最大功率追蹤電路架構,其中返馳式轉換器、功率因數修正器、升壓降壓轉換器為電力電子乙級測試電路,以不同量測條件分別測試上述三種電路架構,而太陽光電發電系統使用HJT太陽能電池及PERC太陽能電池組成之太陽光電模組作為輸入電源。 本文利用Powersim套裝軟體模擬上述三種電力電子乙級測試電路及太陽光電發電系統最大功率追蹤電路架構並分析量測波形及模擬結果,太陽光電發電系統最大功率追蹤電路架構,透過擾動觀察法最大功率追蹤技術及全橋式變流器之控制建立併聯型太陽光電發電系統之模型,藉以探討太陽能模組串列先作最大功率追蹤再並聯及太陽能模組串列先並聯再作最大功率追蹤,2種架構在不同日照及部分模組遮蔭下輸出功率的差異,得出太陽能模組串列先作最大功率追蹤再並聯的架構其輸出功率效果較佳。

This paper aims to measure the actual waveform of the flyback converter, power factor corrector, boost-buck converter and use Powersim package software to analyze three circuit architectures and the maximum power point tracking circuit architecture of solar photovoltaic systems. The flyback converter, the power factor corrector, and the boost-buck converter are power electronic class B test circuits, and the above three circuit architectures are respectively tested under different measurement conditions. The photovoltaic system uses a solar photovoltaic module composed of a HJT photovoltaic cell and a PERC photovoltaic cell as an input power source. This paper aims to use Powersim package software to simulate the above three power electronic class B test circuit architecture and the maximum power tracking circuit architecture of the solar photovoltaic system and analyze the measurement waveform and simulation results. Through the disturbance and observation method of maximum power point tracking and full-bridge inverter control to establish a grid-connected photovoltaic power generation system. So as to discuss the difference between the output power of the solar module series first for maximum power tracking and parallel connection and the solar module series parallel connection first and then for maximum power tracking under different irradiation and partial module shading. The conclusion is drawn that the output power of the solar module series first for maximum power tracking and parallel connection is better. This study could provide a reference for designing and setting photovoltaic power generation systems.
