Transformers are passive electromagnetic components used in power electronics to transfer energy between circuits through magnetic coupling. They operate by converting electrical energy into a magnetic field and back into electrical energy, enabling controlled voltage and current transformation between isolated or non-isolated windings.
Within the Power category, transformers are commonly recognized for their role in:
- Voltage conversion between different circuit levels
- Galvanic isolation to separate electrical domains
- Impedance transformation to support efficient power transfer
Transformer products are generally differentiated by their construction and intended operating method, such as power-frequency types and high-frequency types used in switching power conversion.
