High-Efficiency Transformer-Rectifier Unit: Design and Experimental Studies

The paper presents the results of studies of a transformer-rectifier unit for the aircraft power supply system. To increase the efficiency, amorphous magnetic material is used for the transformer magnetic core. According to the results of calculations, a computer model of a transformer-rectifier unit was developed. An assessment of the feasibility of using amorphous magnetic material for the transformer magnetic core of a 12-pulse transformer-rectifier unit of an aircraft was made. A prototype of a transformer-rectifier unit with a magnetic core made of amorphous magnetic material was developed according to the results of calculations and computer simulation. The simulation results were verified by the experimental studies.
