The Iron core and windings play a key role in defining the characteristics of a transformer. There are a number of different transformer shapes available. Circular, oblong (oval) and rectangular shapes are the most commonly used. In this post we will investigate the difference between these shapes, and which shape offers the most benefits.
Amorphous core transformers are manufactured using ferromagnetic amorphous metal formed into thin foils. Their higher resistance and thinner foils have been proven to lead to low losses and better resistance to harmonic wave. The use of amorphous metal transformers gradually gained popularity, particularly throughout India and China who have been using them since about 2005. Europe and the USA have been slightly more cautious to use this type of transformer, due in part to the higher labour costs of production.
