Abstract (en)
[origin: CN106504869A] The invention relates to a transformer (2), in particular a medium - frequency transformer, for use in an inverter (1), comprising: a transformer core (21), a multi-core winding (22) having a plurality of wires (22a, 22b) around the transformer core (21), each of the wires (22a, 22b) forming a winding branch (24a, 24b); terminals (23) at which respective ends of the wires (22a, 22b) are electrically connected to each other; an inductive coupling (5) for inductively coupling the winding branches (24a, 24b) in pairs so as to compensate for parasitic branch currents in the winding branches (24a, 24b).
Abstract (de)
Die Erfindung betrifft einen Transformator (2), insbesondere Mittelfrequenztransformator, zur Verwendung in einem Umrichter (1), umfassend: - einen Transformatorkern (21), - eine mehradrige Wicklung (22) mit mehreren Drähten (22a, 22b), die um den Transformatorkern (21) gewickelt sind, wobei jeder der Drähte (22a, 22b) einen Spulenzweig (24a, 24b) bildet; - Anschlüsse (23), an denen jeweils die entsprechenden Enden der Drähte (22a, 22b) miteinander elektrisch verbunden sind; - eine induktive Kopplung (5), um die Spulenzweige (24a, 24b) paarweise miteinander so induktiv zu koppeln, dass sich parasitäre Zweigströme in den Spulenzweige (24a, 24b) kompensieren.
