Transformer Category Description

Transformers are indispensable core equipment in power systems. Through the transformation of voltage and current, they provide technical support for the transmission and distribution of electricity. Our transformer product categories provides you with the following types of transformers: audio transformers, current detection transformers, isolation transformers and autotransformers (step-up/step-down), power transformers, pulse transformers, switching converters, SMPS transformers

Transformer definition

Transformers are electrical devices used to change AC voltage and current. It transfers electrical energy from one circuit to another through the principle of electromagnetic induction and can adjust the voltage level.

Working principle of transformers

The operation of transformers is based on Faraday's law of electromagnetic induction. It consists of two or more inductively coupled coils (windings) that are wound on a common magnetic core. When AC is passed into one winding (primary winding), an alternating magnetic field is generated in the magnetic core, which in turn induces an electromotive force (voltage) in the other winding (secondary winding). By adjusting the turns ratio of the primary and secondary windings, the voltage can be increased or decreased.

Classification of transformers

Transformers can be divided into step-up/step-down transformers, isolation transformers, autotransformers and instrument transformers according to their functional types.

What is an audio transformer?

An audio transformer is a transformer specially used for audio signal processing. It uses the principle of electromagnetic induction to achieve signal isolation, impedance matching, signal balance and other functions in audio circuits. Audio transformers are widely used in audio equipment, communication equipment, broadcasting systems and musical instrument amplifiers.

What is a pulse transformer?

A pulse transformer is a transformer specially used for transmitting and processing pulse signals. Unlike traditional power transformers, the design and function of pulse transformers are aimed at rapidly changing electrical signals, so they are widely used in applications such as transmission, coupling and isolation of pulse signals. Pulse transformers are commonly found in digital circuits, radar systems, communication equipment and power electronic equipment.
