Transformer Cores: Basic Characteristics & Working Principle

The transformer core serves as the central component for electromagnetic conversion. Constructed primarily from stacked high-permeability materials, its function is to establish a closed magnetic circuit, providing a stable pathway for magnetic flux transmission. Through alternating magnetic fields, the core facilitates voltage transformation by converting electrical energy from the primary side into magnetic energy, which is then reconverted into electrical energy on the secondary side, thereby completing energy transfer and voltage regulation.
