The invention discloses a parallel type high-power boost conversion processing system and a fuel cell power supply system. The boost conversion processing system comprises a conversion controller and a plurality of conversion modules electrically connected with the conversion controller in a parallel mode. A current loss table is arranged in the conversion controller, and the conversion controller calculates the number of conversion modules to be started according to the current input total power, the preset input total current and the current loss table, so that the total power loss of all the started conversion modules is minimum, and the input total current is equally distributed to the started conversion modules; according to the boost conversion processing system, an electrical parallel structure and a centralized control mode are adopted, and when the system is started, the output current of the output end of the fuel cell system can be prevented from jittering; the operation of the whole machine is not influenced when any conversion module fails, so that the whole machine is high in fault resistance and good in stability, the fault is easy to check after the fault occurs, in addition, the power loss of the whole machine is minimum, and the conversion efficiency of the conversion module is effectively improved.

    本发明公开一种并联式大功率升压变换处理系统及燃料电池供电系统,其中该升压变换处理系统包括一变换控制器和若干以并联方式与变换控制器电性连接的变换模块;变换控制器中设置有电流损耗表,变换控制器根据当前输入总功率、预设输入总电流和电流损耗表计算所要启动的变换模块的个数,以使得所启动的所有变换模块的功率总损耗最小,且使得输入总电流均分到所启动的若干变换模块中;上述升压变换处理系统,采用电气并联结构和中心化控制方式,开机时,可避免燃料电池系统输出端的输出电流抖动;任一变换模块出现故障不会影响整机的运行,使得整机抗故障能力强,稳定性好,而且出现故障后易于排查,另外,整机的功率损耗最小,从而有效提高变换模块的转换效率。
