Single phase 1-kVA amorphous core transformer: design, experimentaltests, and performance after annealing

The design and experimental implementation of a single-phase power transformer operating at 1 kVA, 110/220 V, and 60 Hz, with an amorphous alloy core are described. The prototype core material is annealed in an argon atmosphere, under a DC magnetic field applied along the ribbon length. The experimental results are presented to compare the amorphous core transformer performance with another transformer with the same rated power, but with a silicon steel core
