2024 年省大学生电子设计竞赛实验报告无线电能传输装置(F 题)2024 年 8 月 15 日摘要:本设计基于磁耦合式谐振荡电路来进行无线电能传输,点亮 LED 灯。由于输入和输出都是直流电的形式,因此本系统将分为以下四个部分:第一部分为驱动电路( DC-AC),为使直流重量转化成沟通电并通过耦合线圈将电能传输给负载,采纳 LC 谐振的方式让回路中电容和电感构成一个二阶 LC 谐振电路,驱动 MOS 管形成沟通电。第二部分为发射电路(AC-AC),应用电磁感应原理,在二次线圈中产生感应电流并输给接受电路。第三部分为电能转换电路(AC-DC),输出的感应沟通电经整流桥桥式整流后流入升压电路。第四部分为升压电路(DC-DC),对整流之后的直流进行升压,防止整流后的电压无法驱动LED。本设计分模块搭建并对各个部分电路进行原理分析。在调试时,采纳分模块调试,根据调试结果修改参数,最终形成一个完整的稳定系统。关键词:磁耦合式谐振荡电路 LC 振荡电路 桥式整流 DC-DC 升压[Abstract]Thedesign is based onmagneticresonanceoscillationcircuitcoupledtothe wireless power transmission, litLEDlights.Since the inputand outputarein the form ofdirect current, so the systemwill be divided intothe followingfourparts: The firstpartofthe drive circuit(DC-AC),isconverted intoalternating currentso thatthe DC componentandthepower transmissionthrough the coupling coilto the load, using LCresonantcircuitina mannerso thatthe capacitance and inductanceformasecond orderLCresonant circuit, the ACdriveMOStube formation.
