A transformer is a static electromagnetic device that has two or more inductively coupled windings on a magnetic circuit and is designed to convert one or more AC systems (voltages) into one or more other systems (voltages) by electromagnetic induction, without changing the frequency.
The transformer performs AC voltage conversion and/or galvanic isolation in a wide variety of applications - electrical power, electronics and radio engineering.
Structurally, a transformer can consist of one (autotransformer) or several insulated wire or tape windings (coils) covered by a common magnetic flux, wound, as a rule, on a magnetic circuit (core) made of a ferromagnetic soft magnetic material.
The operation of a transformer is based on two basic principles:
- A time-varying electric current creates a time-varying magnetic field (electromagnetism).
- A change in the magnetic flux passing through a winding creates an EMF in this winding (electromagnetic induction).
One of the windings, called the primary winding, is energized from an external source. The alternating magnetizing current flowing through the primary winding creates an alternating magnetic flux in the magnetic circuit. As a result of electromagnetic induction, an alternating magnetic flux in the magnetic circuit creates in all windings, including in the primary, an induction EMF proportional to the first derivative of the magnetic flux, with a sinusoidal current shifted by 90°in the opposite direction with respect to the magnetic flux.
Some transformers operating at high or ultrahigh frequencies may not have a magnetic circuit.
The shape of the voltage in the secondary winding is related to the shape of the voltage in the primary winding in a rather complex way. Thanks to this complexity, it was possible to create a number of special transformers that can act as current amplifiers, frequency multipliers, signal generators, etc.
