基於微控制器達成的 D 類放大器數位調變方法
指導老師:謝冠群   組長: 翁偉吾   組員:管冠傑 蔡牧恆
能源議題日益顯著,電子電路中的能源轉換效率是典型的省能指標。然而,相較傳統架構之放大器,高效率的D類放大器需在失真、效率、與穩定度之間權衡。因此,調變訊號之方法需不斷改良,使系統能在上述三項指標中達到最好的表現。透過MCU進行涵蓋周邊控制電路與調變器的整合,可以省去複雜的電路成本;也可以對於訊號做更精確的調變,更重要的是,對於開發與修正,具有便利性,使系統價值提升。
Power converting efficiency has become a general topic
of designing electronic circuits. However, the high-efficiency Class D amplifier possess some drawbacks. It needs to acquire low output distortion, high efficiency and an adequate system stability. Therefore, improving the modulation process became important to optimize the performance.
The implementation of the signal modulation together with the other
system control functions via MCUs would be a low-cost solution.
No complicated external circuitry is required. Better and precision signal is produced. Last but not least, the solution provides easy-maintenance of the system and a higher product value.
我們決定將壓電陶瓷晶片和鞋子做結合。
