【 摘 要 】
This paper considers a method of reducing idling losses with the use of amorphous steel for a magnetic core for an eighteen-pulse transformer rectifier unit for the aerospace application. Numerical calculations of transformer rectifier units with various types of amorphous alloys were carried out to determine the mass and overall dimensions and idling losses. To determine the shape, amplitude and harmonic composition of the eighteen-pulse rectifier, an imitation simulation of a three-to-nine-phase rectification system was carried out. In order to determine the maximum temperatures with a nominal mode, a computer simulation of the thermal fields of the transformer rectifier unit was carried out. To verify the numerical calculations, simulation and computer simulations, experimental studies were carried out on the developed demonstration layout.
