Hybrid Magnetic Core for Perspective Supply System of the Aircraft

This paper deals with the problem of reducing efficiency and increasing the weight and overall dimensions of the power supply system of the aircraft. The way of its solution by using a hybrid magnetic core is proposed. A review of application of various alloys as magnetic cores of transformers for the improving their characteristics was carried out. A hybrid magnetic core design is proposed for combining the properties of various alloys. The features of amorphous and precision magnetically soft alloys are considered, their advantages and disadvantages are determined. A method for calculating the magnetic characteristics of a transformer with a hybrid magnetic core is shown. To confirm the proposed solution of the problem, a transformer-rectifier unit with hybrid magnetic core was calculated. It is revealed that the use of a hybrid magnetic core based on amorphous and precision magnetic soft alloys will increase their efficiency while reducing weight and overall dimensions.
