What are medical-grade transformers?

Have you ever asked the question, “What is the difference between medical-grade transformers and non-medical grade transformers?” Medical Grade Transformers are almost exclusively isolation transformers that satisfy many safety guidelines and rules beyond the requirements needed for transformers that are not medical-graded. They are designed to isolate the patient and the operator from an electric …

What Are Electrical Transformers?

Transformers are electrical devices with the capacity to change the voltage level of an alternating current (AC) in a circuit. They function only with AC circuits, not with direct current (DC) circuits. The basic components of a transformer are two separate coils of wire wound around a single core. The coil connected to the incoming …

An Introduction to Toroidal Power Transformer

As you might already know, transformers are devices that transfer power between two parts of an electrical circuit by creating isolation with varying currents and voltage. They are an integral part of almost all electrical applications. Power transformers are used when high-efficiency power transfer is needed. Depending on the specific application, devices may operate continuously or …

Choosing Cores for different SMPS topologies

The selection of the magnetic components (transformer cores) to be used in a Switch Mode Power Supply (SMPS) design is the most important element of that process. Understanding the topologies of SMPS’ is crucial as the designer must consider the trade-offs between them. This article will give you an overview of these tradeoffs. Numerous circuits …

Autotransformer vs Isolation Transformer

An isolation transformer is an electrical transformer with a primary and secondary coil winding. These windings are separated by insulation. This insulation limits the risk of electrocution when the active parts and earth are touched simultaneously. An autotransformer is an electrical transformer with only one winding. The term “auto” refers to single-coil acting alone and not to any automatic …

What are balun transformers?

balun tranformer

In the world of electronics, it’s common to hear about two varieties of lines—balanced and unbalanced. Balanced lines have two conductors, which feature equal currents running in opposite directions. An example of balanced lines is twisted pair cables. On the other hand, unbalanced lines feature just one conductor and ground, like a coaxial cable. Baluns …
