平面高频变压器的设计与仿真

Design and simulation of planar high-frequency transformer

针对传统绕线变压器存在体积大、易产生电磁干扰等问题,提出在某些特殊情况下,应采用平面高频变压器替代。分析了平面高频变压器的结构特点,给出了其设计公式,运用ANSOFT公司的PEMAG软件设计了满足实验要求的变压器模型,并且将模型导入到Maxwell有限元分析软件中对各项参数指标进行了定量评估。

Since the traditional winding transformer, the volume of which is large, easily causes etectromagneuc disturbance,this paper proposes to replace the traditional transformer by planar high-frequency transformer under some special circumstance, the structural characteristics analysis and design equation of which are as well made. PEMAG of ANSOFF is applied in the design of the transformer model, meeting the requirements of the laboratory, which is brought in the Maxwell finite element analysis software for the quantitative evaluation of parameters index.
