Coils & Transformers

UPE's coils and transformers are built using a printed circuit board process that produces a very compact package with excellent repeatability in electrical characteristics. Heavy Copper PCBs eliminate the challenges associated with the traditional wound planar transformers.

Attributes

Power DensityPlanar construction yields a smaller package than the industry-favored alternatives.

Case Studies & Testimonials

Planar TransformerUPE developed a transformer for a 30-Watt supply with power-factor correction implemented in transition mode, using an L6562 controller and operating over the worldwide range 85 to 265V AC. The primary and control-power windings require 2kV of insulation rating from the secondary – something easily achieved in a PCB planar transformer, but more difficult in a low-power wire-wound version where creepage distances take up much of the available traverse on a small bobbin.
