數位化市電併聯型燃料電池發電系統電能轉換之研究

本論文以數位化市電併聯型燃料電池發電系統電能轉換做研究，為了達到環境保護故使用綠色能源作為發電系統搭配數位訊號處理器(TMS320F28335)設計及分析，並使用模擬軟體(PSIM)對昇壓型轉換器與全橋式變流器建構模型，以針對各元件相關數值及工作原理進行探討。本研究由1.2kW質子交換膜燃料電池作為發電系統，本系統之升壓轉換器以一顆MOSFET做為控制元件，由DC38V升壓至DC200V，再經由變流器，則變流器是以四顆IGBT做為變流器主要控制元件，產生AC110V再與市電併聯，而MOSFET與IGBT都經由數位訊號處理器(TMS320F28335)產生PWM與SPWM輸入，本文市電併聯型之整體轉換效率為72%以上。加入了被動形孤島效應之檢測，使其當市電停止或故障時可及時跳脫暫停供給市電。以數位訊號處理器達到數位化資料處理與系統的執行，燃料電池做為併網市電之電源，故符合現今資訊化與數位化綠色能源，以環境保護及永續發展之理念。

This paper is about conversion for digitizing grid-connected fuel cell power system research. Use green energy power with digital signal processor (TMS320F28335) as the generation system in order to protect environment, also use simulate software (PSIM) to construct a model for boosting the converter and the full-bridge inverter, and discuss each correlative value and works. The generation system is by 1.2kW proton exchange membrane fuel cell, and the boost converter is by a MOSFET controlling. DC38V boosted DC200V through the converter; the converter used of four IGBT as an inverter controller, output AC110V with grid-connected. The MOSFET and IGBT output PWM and SPWM via digital signal processor (TMS320F28335), this grid-connected efficiency is over 72%. Also join the islanding detection, so when the grid-connected failure, it can suspend supplying grid-connected. Digital signal processor achieved digital data processor and system implementation; fuel cell as grid-connected power, it conforms today’s information and digital green energy, concept of protecting environment and sustainable development.
