The invention relates to a power and onboard electric energy system for an all-electric aircraft and a related power supply system. The power electric energy system comprises a plurality of batteries used for providing electric power; a plurality of DC/DC converters, each of the plurality of DC/DC converters being electrically connected to a corresponding one of the plurality of batteries so as to perform DC/DC conversion on the direct current output by the battery; a plurality of switchboard boxes, each of the plurality of switchboard boxes being electrically connected to an output of at least one of the plurality of DC/DC converters to receive the DC current converted by the DC/DC converter; and a plurality of DC/AC inverters, each of the plurality of DC/AC inverters being electrically connected to an output of one of the plurality of switchboard boxes to convert a direct current output from the switchboard box into a three-phase alternating current, thereby providing electrical energy to a drive of the all-electric aircraft.

    本公开涉及全电飞行器的动力和机载电能系统及相关的电源系统。动力电能系统包括:用于提供电力的多个电池;多个DC/DC转换器,所述多个DC/DC转换器中的每一者电连接到所述多个电池中的相应一个电池,以对该电池所输出的直流电进行DC/DC转换;多个配电盘箱,所述多个配电盘箱中的每一者电连接到所述多个DC/DC转换器中的至少一个DC/DC转换器的输出,以接收经DC/DC转换的直流电;以及多个DC/AC逆变器,所述多个DC/AC逆变器中的每一者电连接到所述多个配电盘箱中的一者的输出以将来自配电盘箱的直流输出转换成三相交流电,由此向所述全电飞行器的驱动装置提供电能。
