中文摘要 本論文的第一部分在描敘無線充電系統的主要幾個元件所扮演的角色與設計方法,分別為發射端的RF信號源、功率放大器、發射的dipole天線,以及接收端的接收patch天線、高敏靈度射頻整流電路倍壓器、電壓調節器、電池電壓紀錄器及充放電曲線紀錄繼分析程式。
目前已實現的充電系統為916.5MHz頻段的無線功率充電系統,信號源採用的是文星的ASK調變的射頻模組,將欲發送的信號調變至916.5MHz頻段,此一模組最大發射功率為4dBm,經由RFMD型號為RF2173的功率放大器放大26dB後,發送30dBm功率至天線。接收端主要是由rectenna及充電裝置組成。Rectenna是Rectify antenna的簡稱,乃由一天線及高頻整流電路所構成,高頻整流電路能夠將微波信號經由Schottky barrier diode整流成直流電源,在此所使用二極體型號為Hitachi的1SS106的二極體,此一二極體普遍使用於RF detector及High speed switch上,藉此作為無線功率傳送研究的開端,目前發展出以此二極體作為Rectenna有916.5MHz與2.45GHz頻段,能夠有效地將射頻能量轉成直流電源,以供充電之使用。在充電應用上,本團隊與化工系的鋰電池研究結合,並討論無線充電對於鋰電池的各種效應與現象,並紀錄電池在充電過程中的電壓變化曲線,同時控制充電放電,以供研究人員有效率地分析電池的各種參數。
  第二部份則專門討論整流電路的各種實驗結果與設計方法,利用Agilent Network Analyzer量測出二極體的串聯小信號模型,再使用適當的匹配網路將微波導入Voltage Doubler架構的二極體中,再比較此一二極體在適當匹配後於不同頻段的差異,在實驗中,發現到二極體在不同的輸入功率下,將會明顯的等效阻抗改變,此一特性在實際應用上將有很大的影響,這將是一個值得探討改進的題目。
英文摘要 The first section of this thesis is describing the main components of wireless powering system, the roles that they perform in this system and the design method of them. The components of transmitter of this system are RF (Radio Frequency) signal generator, RF power amplifier and dipole antenna. At receiver, the components are spiral antenna, high sensitivity RF rectify circuit, voltage regulator, battery charging, discharging curve acquisition circuit and Labview analyzing program.
The realized charging system is wireless powering charging, discharging system at 916.5MHz. The signal source of this system is ASK RF modulator which modulating base band signal to 916.5 MHz. The measured maximum output power of this ASK modulator is 4 dBm. By using the 800~950MHz power amplifier of RFMD to add 26 dBm, the output power is up to 30dBm to be transmitted to the antenna. And the receiver mainly consists of rectenna and charge circuit. The rectenna is the abbreviation of rectify antenna composed of one receiving antenna and RF rectify circuit. The RF rectify circuit can rectify microwave by Schottky barrier diode to DC source. The Schottky barrier diode used here is HITACHI diode of 1SS106. This diode is usually used as RF detector or high-speed switch. The completion of this charge system can be the begging of the research of wireless powering. The developed rectenna are at 915MHz and 2.44GHz that can rectify the RF electromagnetic wave to DC. The rectenna can be used to charge with a regulator. In the charging application, we cooperate with chemical engineering to research the effect of wireless charging and discharging of Lithium Ion battery by recording the voltage curve of that battery. Let the researcher to analyze the characteristic of that battery easily.
The second section of this thesis is focused on the design method of rectify circuit. Making use of Agilent Network Analyzer to get the S-parameter of the diode to design the matching network from antenna to diode, then comparing the difference at different frequency. In experiment, we find that the diode has different impedance at different power level. This characteristic of diode will have significant influence in practical situation. This will be a good project to be discussed in the future.
