I. What Are Power Transformers?
A power transformer is an electrical device that uses the principle of electromagnetic induction to transfer alternating current (AC) voltage from one circuit to another. Its primary function is to step voltage up or down to meet the varying voltage requirements of electronic devices. By adjusting the ratio of turns between the primary and secondary coils, transformers regulate the output voltage, ensuring the proper operation of electrical circuits.
II. Working Principle
The operation of a power transformer is based on Faraday's law of electromagnetic induction. When AC current flows through the primary coil, it generates a changing magnetic field. This magnetic field is transmitted through the transformer's iron core to the secondary coil, inducing an electromotive force (EMF) in the secondary coil. The output voltage is proportional to the ratio of turns between the secondary and primary coils. By adjusting this turns ratio, the transformer can increase or decrease the voltage accordingly.
III. Features and Advantages
· High-Efficiency Energy Transfer: Through optimized design and material selection, power transformers achieve low energy loss and high conversion efficiency.
