基于松耦合变压器的无线电能传输技术研究

Research on Wireless Power Transfer Technology Based on Loosely Coupled Transform

电能的无线传输一直是研究的热点。然而受限于安全和技术因素,以微波、激光为载体的无线输电手段现阶段很难获得大规模应用,所以基于感应耦合的无线电能传输技术是目前最容易实现的无线输电手段,而松耦合变压器是特定环境中效率最高的无线输电手段。通过理论推导与软件仿真相结合的方式,研究了影响松耦合变压器系统电能传输效率的主要因素,并利用ANSYS有限元软件对不同类型的铁心结构的松耦合变压器的传输效率进行了仿真计算。

The wireless power transfer(WPT)is always a hot research topic.However,limited by security and technical factors,currently it is difficult to obtain large-scale application of wireless power transmission using microwave and laser as carriers,so WPT technology based on inductive coupling is the easiest means to achieve wireless power transmission.Loosely coupled transformers are the most efficient means of wireless transmission in a specific environment.The main factors affecting the power transmission efficiency of loosely coupled transformer system are studied by means of theoretical derivation and software simulation,and different types of core design are simulated by ANSYS finite element software.
