Top 12 Power Transformers

Power transformers play the role of a handy tool more often than not when one is working with electrical devices. However, selecting a power transformer that is perfectly suited to your needs requires you to have some prior knowledge about the product, and that's precisely what this guide aims to do.

Power Transformers Buying Guide

The purpose of a power transformer is to transfer electrical power from one circuit to another without altering the frequency. The advantages of a power transformer are many. They are a relatively inexpensive and low maintenance way to control and stabilise voltage transmission. Not to mention that they generally do not require any starting time. If you work in the field of electronics, a power transformer is a necessity.

Types of power transformers

There are various kinds of power transformers available in the market. The most common types include isolation transformers, autotransformers, and flyback transformers. Isolation transformers have two distinct coils which are separated in a way that they can provide electrical isolation between two separate coils. Autotransformers only have one wound coil, and they can produce several output voltages from just one input voltage. Flyback transformers, also known as line output transformers, are specialised transformers initially designed to control the CRTs or cathode ray tubes in monitors and televisions.

Step Up vs Step Down

Step-up transformers and step-down transformers are two kinds of transformers that serve contrasting purposes. Step-up transformers convert the high current and low voltage from the primary side of the transformer to the low current and high voltage value on the secondary side of the power transformer. On the other hand, step-down transformers convert the low current and high voltage on the transformer's primary side to the high current and low voltage value on the power transformer's secondary side. Depending on what your requirements are, you may need a step-up or a step-down power transformer.

Specifics on construction

Power transformers can be made of different types of core materials. Laminated transformers come with laminated steel cores, insulated with a nonconducting material, which helps to reduce electrical loss. Split-core transformers are built with a unique hinge and locking snap that allows electrical connection without disrupting the working of the current-carrying wire. Toroidal core transformers have copper wire wrapped around a cylindrical core, preventing leakage of the magnetic flux that happens within the coil.

Maximum voltage specifications

Maximum primary voltage indicates the maximum input voltage range, while maximum secondary voltage refers to the maximum output voltage range. A power transformer may be equipped with more than just one input voltage; this can be verified by checking the product details provided by the manufacturer. Therefore, it is necessary to ascertain the maximum primary and secondary voltage required for your specific application.
