摘要:	本論文旨在建立脈波寬度調變(Pulse Width Modulation)信號，於非接觸式感應耦合傳輸通道特性的估計方法。首先從理論推導到出PWM信號的工作週期錯誤(Duty Cycle Error)與感應耦合傳輸通道的接收頻帶寬(Receiver Bandwidth)之關係，同時也推導到出非接觸式感應耦合傳輸系統之轉移函數(Transfer Function)。因不同接收頻帶寬可估計出PWM信號不同的工作週期錯誤(Duty Cycle Error)，由工作週期錯誤估計出解析度(Resolution)，進而利用解析度得到資料傳輸率(Data Rate)。文中除了完成相關理論之推導，並同時進行應用與電腦模擬，藉由MATLAB/Simulink來驗證本論文理論的正確性，由應用與模擬驗證的結果可知，本論文提出之估計方式具有可行性。 This thesis aims at setting up Pulse Width Modulation (PWM) signal for the characteristic calculation method of the communication channel in the coupling of contact-less induction. At first, derive to theory from the relationship of the PWM Duty Cycle Error and the communication channel receive bandwidth of the induction coupling structure. At the same time, derive to the transfer function of the contact-less induction coupling transmission system. Because different receives bandwidth can calculate different Duty Cycle Error of the PWM signal, and then calculation Resolution with Duty Cycle Error, utilize Resolution to get Data Rate. Except finish the deriving of relevant theories in the article, furthermore proceed the application and simulation with the computer, verification the exactitude of the theory of this thesis with MATLAB/Simulink. The result of simulation and application that can know the calculation method in which this thesis puts forward has feasibility.
