The invention relates to the technical field of aviation power supplies, in particular to a preparation method of a high-power direct-current power supply for airplane ground starting, which comprises the steps of main loop design and control loop design. Continuous large starting current can be provided for an aircraft. During specific use, 380V three-phase alternating current is connected, when input voltage changes or loads change, output voltage can be automatically adjusted and stabilized, specifically, the power supply manufactured through the method outputs a specific voltage value + 28.5 V through the design of a three-phase saturable reactor, the design of a main transformer and the design of a control loop, continuous work can be achieved, the power reaches 15KW, and the instantaneous maximum power is 30KW; the device can be used for ground starting and ground power-on inspection of the airplane; meanwhile, the high-power direct-current stabilized power supply can be used in other places needing high-power direct-current stabilized power supplies.

    本发明涉及航空电源技术领域,尤其是涉及一种飞机地面起动用的大功率直流电源制备方法,包括主回路设计和控制回路设计;其能够为飞机提供持续性较大的起动电流;在具体使用时,接入380V三相交流电,当输入的电压变化或负载变化时,可自动调节稳定输出电压,具体而言,该方法制备出的电源通过三相饱和电抗器的设计、主变压器设计和控制回路设计,特定电压值+28.5V输出,可连续性工作,功率达15KW,瞬时最大功率30KW;可供飞机作地面起动和地面通电检查之用;同时,也可以作为其它需要大功率直流稳压电源的场所使用。
