Planar Transformers


Standex-Meder planar transformers offer advantages over wire-wound transformers

Planar transformers are steadily replacing the need for traditional wire-wound transformers in many industries. Electric vehicles, solar inverters, wind power, aviation, healthcare, and industrial manufacturing are just some of the areas where this technology is gaining ground. While the windings of wire-wound transformers are used with round wire, the planar’s windings are built by utilizing flat copper layers (PCBs) or plated flat copper windings (lead frames) to create a laminate-style winding construction. The result is a compact, high-power density planar transformer that is typically 30% of the volume and weight of a traditional wire-wound transformer. This size reduction eliminates many of the design constraints associated with wire-wound transformers, and the planar transformer’s other characteristics offer additional benefits. With a very-low profile, excellent thermal characteristics, high repeatability, and low leakage inductance, planar transformers can easily meet the needs of modern applications.
