Resonant rotating transformer

Abstract

A resonant rotating transformer design increases efficiency while maintaining the small dimensions of devices in which the transformer is used. The inventive concept lacks a ferrite or other metal core and instead uses at least two secondary winding members positioned near a primary winding member on a non-magnetic base. The lack of a ferrite core increases the overall lifespan and efficiency of the resonant rotating transformer while permitting the resonant rotating transformer's small dimensions of substantially under 100 mm, as well as resistance to stress and vibrational loads. The resonant rotating transformer is optimized for holographic fan displays but is useful for other electronic devices. Variations of sequential and parallel alignment for elements of the at least two secondary winding members, as well as various winding arrangements, enable changes of properties of the resonant rotating transformer.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present patent application claims priority to U.S. provisional application 62 / 957,509 filed on Jan. 6, 2020 and U.S. provisional application 62 / 957,534 filed on Jan. 6, 2020.FIELD OF THE INVENTION[0002]The claimed resonant rotating transformer refers to electrical engineering, and more specifically to resonant transformers for contactless transmission of electricity to rotating elements, which can be present, in particular, in radars, in surveillance video cameras, in robotic manipulators, and in display devices such as a holographic fan display.BACKGROUND[0003]There are a number of solutions for transformers. Most of these solutions have a metal conductive core and include primary and secondary windings or coils. When the windings on the primary windings or coils exceed those of the secondary windings or coils, the voltage steps down. When the winding on the primary winding or coils are less than those of the secondary windings or co...
