About Payton's Planar Transformer

While operating under the same laws of physics and using the same materials (i.e. copper, ferrites) like the conventional transformers, these Planetics® planar transformers have different construction geometry that reflects handful of technological advantages.

Planetics® are the state of the art magnetic components in the advanced industry of high frequency SMPS.
The small size and weight of Planetics® enable the designer to minimize the SMPS physical dimensions.

The excellent repeatability, high efficiency (97-99%) and efficient cooling methods have already made Payton's Planetics® the preferred technological choice in many of the world leading electric companies.

This commercialized innovative technology is available at competitive prices compared with conventional technology, while introducing all these advantages for a power range of 10W-10000W in one unit, operating in 50kHz-2.5MHz, for all SMPS topologies.

This technology complies with all safety standards and is UL approved.
