Transformer Working and Construction

A transformer is one of the most common devices found in electrical system that links the circuits which are operating at different voltages. These are commonly used in applications where there is a need of AC voltage conversion from one voltage level to another.It is possible either to decrease or increase the voltage and currents by the use of transformer in AC circuits based on the requirements of the electrical equipment or device or load. Various applications use wide variety of transformers including power instrumentation and pulse transformers. In a broad transformers are categorized into two types namely electronic transformers and power transformers[1-2]. Electronic transformers operating voltages are very low and are rated at low power levels. These are used in consumer electronic equipment’s like televisions personal computers CD/DVD players and other devices.
