Abstract (en)
[origin: WO2020115402A1] The invention relates to an electromagnetic induction device (100) comprising: - a core (200) having a main leg (210) which extends between two ends, and a secondary section (220) which connects the two ends (211, 212) of the main leg (210); and - two windings —a primary (300) and a secondary (400)— wound onto different portions of the main leg (210), the primary winding (300) being capable of producing a magnetic flow referred to as the inductive flow, intended to pass through the secondary winding (400); and - said core (200) further comprises pickup means in the form of at least one tongue (230) which extends from the secondary section (220) and comes between the main winding and the secondary winding (400), said pickup means picking up a portion of the magnetic flow, referred to as the pickup flow, such that said pickup flow is subtracted from the inductive flow passing through the second winding, and reloops backs into the first winding.
