Audio Transformers: Their Different Types!

A transformer is a kind of static electrical device that uses electromagnetic induction to transmit energy between two or more circuits. The transformer has the ability to step up or down signal voltage. The main and secondary windings of the transformer are not connected directly, and the electrical energy is delivered by electromagnetic induction. 

The transformer offers electrical isolation between primary and secondary, which implies from the input to output or vice versa, due to this isolated quality between primary and secondary. Interestingly, they’re of different types and serve multiple functionalities. 

Therefore, to help you differentiate better, experts from Pico Electronics audio transformers have listed down a handful of these transformers. Let’s get started: 

Based On Operations

Step-up Transformer

Step-up transformers are tools used to step up secondary voltage, in proportion to the primary voltage. They accomplish this by increasing secondary windings, relative to the primary windings. A step-up transformer is a transformer that connects the generator to the grid in a power plant.

Step-down Transformer

As the name suggests, a step-down transformer helps step down the level of voltage from lower to higher on the secondary coil side. In such a transformer, the major side of the winding has more turns than the secondary side.

Based On Core Medium

Air-Core Transformer

In this type of transformer setting, the secondary and primary windings are both coiled on a non-magnetic strip, with the flux connection between them being through the air. The mutual inductance of an air core is lower than that of an iron core, implying that the reluctance supplied to the produced flux is higher in the air medium. In an air-core type transformer.

Iron Core Transformer

In this type of transformer setting, The main and secondary windings are both wound on several iron plate bunches, providing a perfect connection path to the produced flux. Because of the magnetic and conductive properties of iron, it provides less resistance to the connection flux. These are common transformers with good efficiency when compared to air core transformers.

Listed above were some of the majorly used transformers, as suggested by experts at Pico Electronics audio transformers. Since different transformers serve different purposes, here’s an overview of the different applications on types of transformers in the following section. 

Different Applications Of Transformers

• Within a power distribution network, the power transformer is used to enhance or reduce voltage.

• To provide cost-effective electricity distribution, a three-phase transformer is employed.

• Autotransformers and two-winding transformers are commonly used to boost or reduce the voltage from the transmission to distribution networks.

• The main purpose of a distribution transformer is to lower the voltage for distribution to commercial and residential consumers.

• Instrument transformers are used to reduce high voltage and current so that they may be measured and carefully utilized with traditional equipment.

• A single-phase transformer is commonly used to supply electricity for receptacles, household lights, air conditioning, and heating.

• Electrical substations for power distribution employ oil-cooled transformers.

• Air-cooled transformers are a low-cost way of allowing a lower but otherwise greater voltage rating to work effectively.
