本論文提出一適用於小型風能轉換系統之最大功率追蹤晶片。有別於傳統的昇壓型整流器架構，此風能轉換系統使用了全控制整流器作為前端交流－直流轉換器以達成低電流協波失真以及高轉換效率；低電流協波失真有助於減少由於扭矩漣波所造成的機械諧振；高轉換效率有助於縮短系統投資回收期。本論文提出了一發電機轉速偵測電路，在不需要微處理器或是數位訊號處理器的協助下也可以計算出目前系統的轉速，使得系統可靠度提高、更加密集以及降低成本。
最後，設計出一個具有轉動慣量模擬的測試平台以進行更加準確的系統驗證，並且實現一個200瓦的風能轉換系統，其平均電流協波失真小於3%，最大轉換效率到達95.2%。此控制晶片使用台灣積體電路製造股份有限公司所提供之0.35m 2P4M 3.3/5V混合訊號互補式金氧半製程所製造，全晶片面積為1.107 x 1.117 mm2。

The design and analysis of the MPPT controller for small-scale wind energy conversion system is presented in the thesis. Different from applying a conventional boost rectifier as an AC/DC converter, this work applies the full-controlled rectifier as an AC to DC interface to achieve low current total harmonic distortion (THD) and high conversion efficiency. The low current THD in generator output can reduce the mechanical oscillation introduced by torque ripple, and high conversion efficiency can shorten the system payback period. The proposed rotational speed detection (RSD) circuit provides an elegant and accurate way to detect generator speed without the help of microprocessor or DSP which makes the system more reliable, compact and cost effective.
Finally, a test rig is proposed with moment of inertia simulator to verify the performance of proposed controller more accurately. A 200W prototype is presented, and the experimental results shows the average current THD is less than 3% and with 95.2% maximum conversion efficiency. The die area is 1.107 x 1.117 mm2, and it is accomplished with TSMC 0.35m 2P4M 3.3V/5V CMOS process.
