电气传动2023年第53卷第3期ELECTRICDRIVE2023Vol.53No.3摘要：自动导引运输车（AGV）电池组的无线充电要求是低压大电流，全波同步整流（FWSR）可以提高效率并降低成本。首先详细介绍了AGV无线充电拓扑和工作原理，其次针对实验过程发现的同步整流管电压尖峰问题，进行了理论建模和过程原因分析，并提出了有效的抑制措施和吸收电路设计，最后设计了一台样机，通过实验验证了方案的有效性。实验结果表明，该系统实现了3kW的运行功率，效率可达91%以上，采用同步整流有效提高了系统功率密度。关键词：感应耦合式无线充电；全波同步整流；谐振；漏感中图分类号：TM724文献标识码：ADOI：10.19457/j.1001-2095.dqcd24200SuppressionMethodofSpikeVoltageofAGVWirelessChargingbyFull-waveSynchronousRectificationTONGZhan'anxin，SUJianhui，ZHANGJian，DUYan（EducationMinistryEngineeringResearchCenterofPhotovoltaicSystem，SchoolofElectricalEngineeringandAutomation，HefeiUniversityofTechnology，Hefei230009，Anhui，China）Abstract:Therequirementsforwirelesschargingofautomatedguidedvehicle（AGV）batteriesarelowvoltageandhighcurrent，full-wave-synchronous-rectification（FWSR）canimproveefficiencyandreducecosts.Firstly，AGVwirelesschargingtopologyandworkingprinciplewereintroducedindetail.Secondly，aimingattheproblemofvoltagespikeofsynchronousrectifiertubefoundintheexperimentalprocess，theoreticalmodelingandprocesscauseanalysiswerecarriedout，andtheeffectivesuppressionmeasuresandabsorptioncircuitdesignwereproposed.Finally，aprototypewasdesignedtoverifytheeffectivenessoftheschemethroughexperiments.Experimentalresultsshowthatthesystemachieves3kWoperatingpower，andtheefficiencycanreachmorethan91%，meanwhile，thepowerdensityofthesystemisremarkablyimprovedbysynchronousrectifier.Keywords:inductivecouplingwirelesscharging；full-wave-synchronous-rectification（FWSR）；resonance；leakageinductance基金项目：国家重点研发计划项目（2021YFB2601403）作者简介：童湛安心（1996—），男，硕士研究生，Email：787830053@qq.comAGV无线充电全波同步整流尖峰电压抑制方法童湛安心，苏建徽，张健，杜燕（合肥工业大学电气与自动化工程学院光伏系统教育部工程研究中心，安徽...
