Frenetic is a power electronics company created with the goal of making magnetics simple. Frenetic is revolutionizing the world of magnetics with A.I. technology, which is replacing the need for outdated engineering methods. The A.I. technology allows designing optimal transformers and inductors, build and test samples in our laboratory and get the best manufacturing solutions for our clients in order to ensure that quality and timelines are respected.
App Note: Planar Transformer with Half Turns
New proposed solution for the transformer was based on a 4-column structure, where the flux cancellations reduce the core losses and allow keeping high power density. The solution was used in an LLC converter, obtaining a power density of 55 W/cm3.
