Amorphous core transformers for induction heating converters at 25 kHz
The design and construction of an industrial 25 kHz, 600 kVA power unit with pancake coils are discussed. Criteria for specifying the rated power of the transformer and a comparison with grain-oriented Si-steel transformers are presented. It is shown that the main advantages of using amorphous alloys in this frequency range, in comparison with grain oriented Si-steel cores, are lower first and total costs of the unit for the same output power, higher efficiency values, and reduction of the weight of the transformer.<>
