【正文】 2014年江蘇省大學生電子設(shè)計競賽實驗報告無線電能傳輸裝置（F題）2014年8月15日摘要：本設(shè)計基于磁耦合式諧振蕩電路來進行無線電能傳輸，點亮LED燈。由于輸入和輸出都是直流電的形式，因此本系統(tǒng)將分為以下四個部分：第一部分為驅(qū)動電路（DCAC），為使直流分量轉(zhuǎn)化成交流電并通過耦合線圈將電能傳輸給負載，采用LC諧振的方式讓回路中電容和電感構(gòu)成一個二階LC諧振電路，驅(qū)動MOS管形成交流電。第二部分為發(fā)射電路（ACAC），應(yīng)用電磁感應(yīng)原理，在二次線圈中產(chǎn)生感應(yīng)電流并輸給接受電路。第三部分為電能轉(zhuǎn)換電路（ACDC），輸出的感應(yīng)交流電經(jīng)整流橋橋式整流后流入升壓電路。第四部分為升壓電路（DCDC），對整流之后的直流進行升壓，防止整流后的電壓無法驅(qū)動LED。本設(shè)計分模塊搭建并對各個部分電路進行原理分析。在調(diào)試時，采用分模塊調(diào)試，根據(jù)調(diào)試結(jié)果修改參數(shù)，最終形成一個完整的穩(wěn)定系統(tǒng)。關(guān)鍵詞：磁耦合式諧振蕩電路 LC振蕩電路 橋式整流 DCDC升壓[Abstract]The design is based on magnetic resonance oscillation circuit coupled to the wireless power transmission, lit LED lights. Since the input and output are in the form of direct current, so the system will be divided into the following four parts: The first part of the drive circuit (DCAC), is converted into alternating current so that the DC ponent and the power transmission through the coupling coil to the load, using LC resonant circuit in a manner so that the capacitance and inductance form a second order LC resonant circuit, the AC drive MOS tube formation. The second part is the transmitter circuit (ACAC), application of the principle of electromagnetic induction, induced current in the secondary coil and lost to accept circuit. The third part is the power converter circuit (ACDC), alternating current output induced by the flow into the booster circuit bridge rectifier bridge rectifier. The fourth part is the boost circuit (DCDC),
