    Abstract: 本文中,實現昇壓轉換器與單相全橋變流器之硬體製作,並以併聯型太陽能模式探討最大功率追蹤的控制使得再生能源發電有最大的輸入功率,第一級利用PWM來驅動昇壓轉換器中的IGBT達到昇壓之效果,並提出以半區間法為基礎,利用輸出功率與輸出電壓關係曲線(P-V曲線)來追蹤太陽能模組之功率峰值並與傳統常見最大功率演算法作比較,藉此顯現出其優點與特色。第二級為單相全橋變流器,透過SPWM來驅動變流器中4顆IGBT以及LC元件將直流電轉變成接近60Hz之正弦波,再透過單相市電併聯之電流預測控制策略來達到市電併聯之目的,使用電力量測儀量測其電力品質中的總諧波電壓失真率、總諧波電流失真率以及功率因數進而符合IEEE Std.1547規範以及台灣電力公司再生能源發電系統併聯技術要點。 而在硬體電路設計方面,包含脈波寬度調變電路、電壓電流回授電路、獨立穩壓電源電路等利用Altium Designer軟體。本論文在最大功率追縱控制與市電併聯控制策略上,配合使用MATLAB/Simulink程式完成控制,進而實現該再生能轉換系統之設計。;In this thesis practiced the hardware production of boost converter and single-phase full bridge inverter. With the type of grid-connected discuss maximum power point tracking made renewable energy generations have the maximum input power. First stage uses PWM to drive IGBT achieve the effect of boost from boost converter and then provided interval halving method utilize the output power and output voltage curve (PV curve) to track the solar modules power of peak and compared traditional maximum power point tracking algorithms displays its advantages and characteristics. Second stage is single-phase full bridge inverter uses SPWM to drive four IGBTs and LC components make DC turn into 60Hz of sine wave and then grid-connected accomplished by the current prediction control strategy, electric power measuring instrument measure its total harmonic distortion voltage, total harmonic distortion current and power factor and so on comply with the requirements of IEEE Std.1547 standard and TPC Renewable Energy Power Systemgrid-connected code. In the hardware circuits design include pulse width modulation circuit, voltage and current feedback circuit, independent power supply circuit and so on by Altium Designer software. For maximum power tracking algorithm and grid-connected control strategy use MATLAB-Simulink software practiced to achieve the renewable energy conversion system completely in this thesis.
