The invention provides an aviation power supply system which comprises an emergency power supply with a power storage unit and a main power supply for supplying power to electric equipment, and when the main power supply cannot receive electric energy provided by power supply equipment, the power storage unit supplies power to the main power supply. Compared with the prior art, the invention has the following technical effects: the flight emergency time is prolonged; the electric power storage unit adjusts a voltage value by using a DC/DC converter of an existing main power supply rectification circuit, and a new converter does not need to be additionally arranged, so that the system structure is simplified; the power storage unit can be charged in the flight process through the power supply equipment and the emergency power supply rectifying circuit, and the time for independently charging the power storage unit in the prior art is saved; the main power supply, the power storage unit and the battery supply power to electric equipment, and multiple guarantees are provided.
本发明提供了一种航空电源系统,包括带有蓄电单元的应急电源和为用电设备供电的主电源,在所述主电源无法接收到供电设备提供的电能时,蓄电单元为所述主电源供电。与现有技术相比,本发明具有如下技术效果:本发明延长了飞行应急时间;蓄电单元利用已有的主电源整流电路的DC/DC转换器调整电压值,无需额外设置新的转化器,从而简化了系统结构;本发明蓄电单元通过供电设备和应急电源整流电路在飞行过程中即可实现充电,省去了现有技术中单独对蓄电单元进行充电的时间;主电源、蓄电单元和电池三路电源为用电设备供电,提供多重保障。
