摘　　要：变压器是电力电子设备中比较重要的部件之一,变压器的特性影响电力电子设备的性能,因此对变压器特性的研究非常重要。根据实验室自制的平面变压器,应用MagNet软件计算变压器的交流电阻及漏感,并且建立了正弦波下变压器特性测量平台。测量结果和计算结果接近,并且获得了平面变压器的损耗,平面变压器的最高效率可达99%。最后进行了脉冲电压下的效率测量。Transformer is one of the comparatively important devices of power electronic equipment.The characteristics of transformer affect the performance of power electronic equipment,thus the study of transformer's characteristics is very important.Based on the planar transformer self-made,the paper computes the resistance and leakage inductance of planar transformer using MagNet software,and establishes an experimental platform to measure planar transformer's characteristics in sine wave.The result of measurement approximates to the result of computation,and the loss of planar transformer is obtained.The highest efficiency of the planar transformer is beyond 99%.At last,the efficiency of the planar transformer is measured under pulsed voltage.
