摘　　要：煤矿物联网系统中包括许多需要电池供电,且24 h不间断工作的设备,如果电池更换不及时,将威胁到安全生产。为解决电池更换频繁,同时避免有线充电过程中易产生过热、过充安全隐患问题,引入无线充电技术,设计基于交错并联、全桥逆变及耦合谐振等技术的三段式、非接触充电方案。利用Simulink软件搭建交错并联Boost、初级Buck、高频逆变及次级Buck单元电路仿真模型。合理设置参数使Boost单元在0.4 s后稳定输出400 V电压,初级Buck单元在0.015 s之后稳定输出311 V电压,再通过高频逆变及次级Buck单元在0.01 s之后可输出理想直流电压24 V,符合系统设计要求,并能提高充电安全性与便捷性。There are many devices in the network of things in the coal mine that needed battery power and could work 24 h a day.If the battery couldn′t be changed in time,safety in production would be threatened.In order to solve the problems of the battery was frequently changed,overheating and overcharging in the charging process,the wireless charging technology is introduced into the charging system,and a three-stage,non-contact charging scheme based on staggered parallel,full-bridge inverter and coupling resonance technology is designed.Simulink software was used to build circuit simulation models of interleaved Boost,primary Buck,high-frequency inverter and secondary Buck units.The reasonable setting of parameters makes the Boost unit output 400 V voltage stably after 0.4 s,the primary Buck unit output 311 V voltage stably after 0.015 s,and the high frequency inverter and the secondary Buck unit output 24 V DC voltage after 0.01 s,which meet the requirements of the system design and improve the safety and convenience of charging.
