摘　　要：在非接触能量传输系统中,松耦合变压器是影响能量传输效率的关键因素之一.对松耦合变压器的磁芯和线圈进行仿真建模,通过改变变压器磁芯和绕组的结构,可得到影响传输效率的关键因素.针对U型磁芯和不同绕组形式传输效率较低的特点,提出了一种改进型变压器.该变压器采用扁平U型磁芯和平面螺旋式绕组,仿真分析可得该改进型松耦合变压器结构可以大大提高系统能量传输的效率.In the contactless energy transmission system, loose coupling transformer is one of the key factors affecting energy transmission efficiency. The model of loose coupling transformer is established in this paper. By changing the structure of the magnetic core and winding, the main parameters which impact loose coupling transformer transmission efficiency have been analyzed. According to characteristics that transmission efficiency is low of the U type core and different winding form, the flat type core and plane winding is used to design loose coupling transformer. Through the simulation and comparison, the new loose coupling transformer structure can improve the system energy transfer efficiency greatly.
