| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士班 === 94 === With the progression of the technology advancement, there are more and more electric equipment produced in our living environment. In that, most of the equipment will result in a magnetic field. Although it is not sure that human is cursed with magnetic field in many researches, more of people believe that human will get hurt when staying in magnetic for a long time. The objective of this thesis is to design a magnetic field generator. This thesis, includes the effect of system optioning in high frequency magnetic field, and the theory regarding simulation. The simulation software is used to build the module and simulate the distribution of the generating magnetic field. This work designs a high frequency magnetic field generator. The frequency of the generator is 100KHz, and the field intensity is 50Gauss. The LC parallel resonant compensation is adopted in the power supply of the magnetic field generator to enhance exciting current and to reduce the secondary current of the high frequency generator. The dimension for the bio-exposure experimental space is 40mm(L) × 40mm(W) × 50mm(H) in the air gaps of the magnetic field generator. Finally, this study utilizes the FEMLAB software based on the finite element method to simulate the magnetic field of generator, and compare the effect between different designs.
