Aiming at the problems that DC/DC converters require low voltage ripple and low current ripple in high-power applications, a fuzzy sliding mode control method for DC/DC converters was proposed to apply in hydrogen fuel vehicles in this work. And a four-phase interleaved boost converter topology was built in this control system by using Matlab/Simulink. The results of simulation evaluation turned out that utilizing the present proposed control algorithm could effectively accelerate the system response speed and reduce the output current ripple and voltage ripple compared with the traditional double closed-loop PID algorithm. Moreover, before and after changing the load, the system showed good dynamics and strong robustness, which could better meet the requirements of automotive DC/DC converter.
