Transformers are essential electrical devices used in
power supply systems to transfer energy between two or more circuits through electromagnetic induction. They work on the principle of mutual induction, where alternating current in the primary coil generates a varying magnetic field, inducing a voltage in the secondary coil.
These devices play a crucial role in voltage conversion, stepping up or stepping down electrical energy for efficient power distribution and transmission. In power supply applications, transformers are employed to adjust voltage levels, ensuring safe and stable electricity delivery to homes, businesses, and industries. Their reliability and versatility make transformers indispensable components in modern electrical systems.
