Calculation, Design and Manufacturing Amorphous Core Small Power Transformers

The amorphous steel core transformer has the advantage of reducing the load loss by up to 70%. Thanks to the special microstructure and composition, it is a small magnetic resistance with very small steel sheet thickness and very high resistivity. Therefore, when used as a magnetic circuit for transformers, there is a significant reduction in no-load losses compared to high-quality silicon steel transformers. This paper presents the design and production of a three- phase transformer with 3kVA, 380/127V. Experimental results in no-load and short circuit modes such as current, voltage, and losses are compared with simulation results with the Ansys Maxwell software. Demonstration of no-load losses of core steel transformers decreases significantly compared with that of silicon steel core transformers. The result has been the introduction of energy efficiency when using small and medium power amorphous transformers for school equipment, factories or in residential areas
