What is a Core Transformer?
Air Core Transformer Definition
An air core transformer is defined as a transformer that uses air instead of a ferromagnetic core to link the magnetic flux between its windings.
Principle of Operation
It operates on electromagnetic induction, where an alternating current in the primary coil induces an emf in the secondary coil.
Construction Types
Air core transformers can be cylindrical, with wires wound on a non-metallic cylinder, or toroidal, with wires wound around a plastic ring.
High-Frequency Suitability
They are suitable for high-frequency applications due to their noise-free operation and avoidance of electromagnetic distortion.
Advantages
These transformers are lightweight and avoid losses and saturation problems associated with ferromagnetic cores, making them ideal for portable electronic devices.
