Research On High Frequency Power Converter Based On Planar Magnetic Element

With the rapid development of drone technology and personal smart devices,cumbersome,low power density power converters have become an important reason for restricting their wide application.Therefore,designing and manufacturing a compact,lightweight,high power density power converter has become the goal of power electronics designers.By increasing the switching frequency,the high-frequency power converter effectively reduces the size and size of the energy storage component of the converter,making the converter more compact and delicate.Therefore,it is of great engineering significance to study the design and application of the high-frequency power converter.First of all,this paper mainly studies the Class-Φ2 high frequency power converter based on air core inductor.The converter design method is described by analyzing the working principle of the converter.Based on this method,the high-frequency power converter that meets the performance requirements is designed.The converter is simulated and verified by LTspice simulation.Combined with theoretical analysis and simulation experiments,a high-frequency converter prototype was designed to verify the feasibility of parameter design through prototype debugging.Secondly,the feasibility of using PCB planar inductor instead of hollow core inductor as energy storage component application and high frequency power converter is studied.Firstly,the parameter design of the planar inductor is used.The Ansoft-Q3 D simulation software is used to simulate the planar inductor of the design,and the error parameters are obtained to correct the planar inductor design.Combined with theoretical analysis and simulation experiments,a high-frequency power converter based on planar inductor is designed for prototype measurement.Through the prototype debugging,verify the PCB plane inductance design and rationality and the feasibility of application in the field of high frequency power converter.Finally,a push-pull Class-E high-frequency power converter based on a planar transformer with a switching frequency of 30 MHz is studied.Simplified design is achieved by decomposing the converter into a rectification stage and an inverter stage.The principle analysis and parameter design of the rectifier and inverter stages are carried out respectively.The LTspice simulation software is used to verify the simulation of the designed high frequency power converter.Based on the parameter design and simulation results,a push-pull Class-E high-frequency power converter prototype was designed.The rationality of converter parameter design and the application of planar transformer and push-pull topology in the field of high-frequency converter were verified by prototype debugging.Feasibility.
