石化燃料的枯竭與溫室效應的影響已遍布世界各地，其中最重要的解決方法即是尋找長久之替代能源。太陽能發電系統正廣泛的被研究，因為它的好處是環保和可再生的特點，與石油、天然氣與煤炭相較之下，不排放溫室氣體或造成汙染，並預期提高的可行性、降低成本和提高轉換效率。本論文的重點是以DSP為基礎發展高性能隔離式微型太陽能系統。取樣PV輸出電壓電流至DSP配合擾動觀察法，在隔離型交錯式升壓轉換器上實現最大功率追蹤並升壓至400V，再配合單相全橋式換流器利用正弦波調變將400V直流轉為220V 60Hz交流，以供一般電器使用。本論文所研究的架構可提供低成本、電路簡單及良好的整體效率，經過實驗室原型系統的製造與測試，實驗結果顯示，證明是一可行性的架構。

While fossil fuels exhaustion and greenhouse effects are widely concerned around the world, one of the most important issues toward to these problems is to find alternative energy for long-term solutions. PV energy systems are being extensively studied because of its benefits of environmental friendly and renewable characteristics. Unlike oil, gas and coals, solar energy does not emit greenhouse gases, or cause pollutions, and is expected to enhance the feasibility of lowering cost and increasing conversion efficiency. This thesis focuses on the developments of a high performance DSP-based isolated micro solar inverter system with maximum power point tracking (MPPT). The input voltage and current of the micro inverter are sensed to realize the MPPT control by perturbation and observation (P&O) method. The isolated interleaved boost converter achieves MPPT and boosts to 400V. With single-phase full-bridge inverter using sinusoidal pulse width modulation modulate 400V DC to 220V 60Hz AC for general electric use. The studied provides the benefits of low cost, simple configuration and good overall efficiency. A laboratory prototype system is built and tested. The experimental results are shown to verify the feasibility of the proposed scheme.
