Patent No. EP2771891 (titled "Inductive Component And Use") was filed by Brusa Elektronik on Oct 19, 2012. The application was issued on Mar 24, 2021.
A choke with improved leakage flux management for power electronics applications. The choke features a main magnetic circuit with a central shank and outer shank, and at least two coils arranged on the central shank. A leakage field guide component, positioned between the coils and separated from the main circuit by air gaps, guides magnetic leakage flux around the coils to prevent eddy currents and thermal loading. The choke design enables efficient power factor correction and energy storage in DC/DC converters.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
