  • Magnetic structures for low leakage inductance and very high efficiency
    Patent number: 10937590
    Abstract: A magnetic configuration utilizing a plurality of posts and spiting the primary winding on each of the posts defining a core and placing the secondary windings together with the rectifier means around each post to minimise the stray and leakage inductance. A significant reduction of the core material and a reduction of the footprint is achieved due to better utilization of the winding material. The magnetic field is weaving from and through one post to the other to minimize the vertical component of ther field and forcing the magnetic field to be parallel with the winding to reduce the AC losses in copper of the winding. These properties allow the magnetic structure to be suitable in very high frequency applications and even in application with an air core. These magnetic structures can be used for implementing a transformer and for inductive applications.
