Airborne 270V power supply unit

The utility model discloses an airborne 270V power supply unit is equipped with the 400Hz intermediate frequency power supply, its characterized in that intermediate frequency power output end is equipped with 270V power control system, 270V power control system comprises filter inductor on main circuit, the main circuit and 270V power conversion module, the intermediate frequency power supply is connected through filter inductor and 270V power conversion module, because filter inductor has the dual function of filtering and step -down, when input 400Hz overtension, the mode realization busbar voltage that steps down through the reactive current on the filter inductor is stably at 270V, by adopting the above structure, the utility model and the algorithm, have novel structure, stable performance, energy efficiency height, convenient to use, light in weight, advantage such as small.
