The DCDC converter of PET is an important part of affecting work efficiency, volume and weight of the device. This paper studies the DCDC converter mainly, then，according to given indexes, main circuit of fullbridge LLC resonant converter is designed in detail, including the design of resonant parameters. And the magnetic integrated transformer is designed with the idea of magnetic integration, which greatly reduces the converter volume, and the selection of devices is pleted on the basis of parameters design. In addition, according to the given parameters, losses of each part and the efficiency are calculated. The results meet the efficiency requirements of design. PEmag and Maxwell simulation software are used to design magnetic integrated transformer, and verified the magnetic integrated transformer parameters. Matlab/simulink is used to simulate and analyze the DCDC converter performance of PET. A prototype of fullbridge LLC resonant converter is developed and system test platform is built according to the theoretical research and simulation results. The correctness and effectiveness of theoretical research and design methods of the DCDC converter are verified by analyzing the waveforms of the test.Key words: power electronic transformer。 LLC resonant converter。 loss analysis。 magnetic integrated transformer WORD格式整理 煤礦井下存在著各種電壓等級(jí)的電源以及電氣設(shè)備，供電系統(tǒng)十分復(fù)雜。為了滿足不同電壓等級(jí)的要求[1]，目前井下常用傳統(tǒng)電力變壓器來進(jìn)行變壓和能量傳遞。這種變壓器制作工藝簡單、可靠性高
