摘要

本研究主要在探討使用升降壓電源轉換器製作太陽能電池模擬系統之電路模擬以及混合供電系統之實務模擬，模擬系統採用Matlab Simulink設計，整體架構可分為升降壓電源轉換器、太陽能電池模擬器、雙模式太陽能電池模擬器、混合供電系統四大部分。首先先從三種常見之升降壓電源轉換器(SEPIC、ZETA、同步式電源轉換器)挑出一組作為設計太陽能電池模擬器之用，並使用此升降壓電源轉換器以電壓及電流迴授之方式設計兩組太陽能電池模擬器，且驗證其系統可行性並探討兩者之優缺點，最後將兩種太陽能電池模擬器並聯產生出雙模式太陽能模擬器，透過模式控制調整兩種太陽能電池模擬器的開關，最後驗證系統可行性及將三種太陽能模擬器作比較。混合供電系統則使用太陽能電池加上最大功率追蹤系統及電池對馬達並聯供電，詳細探討其系統設計與系統輸出狀況，最後成功的驗證太陽能電池模擬系統和混合供電系統之可行性及可靠性。

This thesis discusses the circuit simulations of PV emulator systems with buck-boost power converter and hybrid system simulation. The systems are designed using MATLAB/SIMULINK tools. There are four parts presented in this thesis: buck-boost power converter, PV emulator, dual mode PV emulator and Hybrid system. First, we will choose a buck-boost power converter from three commonly used converters (SEPIC, ZETA, synchronous power converter) for the PV emulators. Using the buck-boost power converter with voltage or current feedback regulation to generate two different PV emulators named voltage regulator and current regulator. Then combine those two regulators to generate dual mode PV regulator, and apply a mode control to switch the mode that control the operation of the regulators. Design results of these three emulators are analyzed in detail. A solar and battery hybrid power system for velocity control of DC motor is also developed using the proposed current regulator. A Simulation model based on MATLAB/SIMULINK and PLECS circuit simulation tools is developed to verify the design.
