Abstract 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.
