Research On Power Supply System Of Electric Vehicle Based On ICPT

Electric vehicles can be used gradually because of its zero pollution advantage with the development and utilization of clean energy.The main limitation of its wide promotion is the traditional charging model is not facility and safety to support the update electric vehicles.In order to solve the problem we can switch the charge way to change traditional connection energy transmission to non-contact power transmission because of its flexibility and security.So in this paper,we mainly consider of analysis and application of inductively coupled power transmission(ICPT)system.First,this paper introduced the current research and application of three kinds of non-contact power transmission technologies.Then comparing the advantages and disadvantages of these three technologies we chose the ICPT as the research object.Secondly,we should know the structure and analysis the working principle of the ICPT system.And then set up an ICPT system model based on mutual inductance model,at the same time comparing advantages of four classical single-stage compensation circuits in ICPT system.Then we want to make LCL resonant converter as compensation topology in ICPT system.So we analysis the working principle of LCL resonant converter and do some calculations of parameters,and then make sure its characters of constant current and constant voltage by simulation.Finally,we can set up an ICPT experiment system by choosing a better solution of separable transformer including magnetic core material and core type.And then the ICPT system transform effect can achieve 50%.
