| Abstract: | The application of hydrogen fuel cell power system in the electric system of mining truck is discussed. The efficiency of the new mining truck system is directly determined by the design of DC/DC converter as the intermediate ring. A magnetic integrated three-phase interleaved bi-directional BUCK-BOOST converter is designed. The operation principle and the designing methods of inductance and capacitance are analyzed and deduced in detail, which shows that the output current ripple of hydrogen fuel cell can be reduced and high voltage DC bus voltage can be stabilized. The MATLAB simulation of the bi-direction BUCK-BOOST converter under each working condition of the mining truck show s that the design method is correct and effective. |
