The invention discloses a 270 V power source device for an airplane. A 400-Hz intermediate-frequency power source is arranged in the 270 V power source device. The 270 V power source device is characterized in that the output end of the intermediate-frequency power source is provided with a 270 V power control system which is composed of a main circuit, a filtering inductor on the main circuit and a 270 V power source conversion module. The intermediate-frequency power source is connected with the 270 V power source conversion module through the filtering inductor. Due to the fact that the filtering inductor has the filtering function and the voltage dropping function, when the input 400 Hz voltage is too high, the busbar voltage can be stabilized at 270 V in the mode of dropping the voltage through reactive currents on the filtering inductor. By means of the structure and the algorithm, the 270 V power source device has the advantages of being novel in structure, stable in performance, high in energy efficiency, convenient to use, low in weight, small in size and the like.
