Is a Single-Phase Transformer AC or DC?

One of the most frequently asked questions when selecting a transformer is: Is a single-phase transformer AC or DC? The answer is straightforward: a single-phase transformer is used exclusively with AC (Alternating Current). This is because its operation is based on electromagnetic induction, which only works with alternating current. A transformer cannot function in DC (Direct Current) systems. In this article, we explore the working principle, technical specs, application areas, and the pricing advantages of WishPower’s single-phase transformers.

Product Description

A single-phase transformer is an AC device that transfers electrical energy between two circuits using electromagnetic induction. It is designed to step voltage up or down in 220V or 240V systems. Comprising a laminated core, primary and secondary windings, it is suitable for small-scale power applications such as lighting systems, control circuits, and home devices. WishPower’s single-phase transformers are known for compact design, energy efficiency, and ease of maintenance.
