Abstract:
Die Erfindung betrifft eine Haltevorrichtung (5) zum Halten eines weichmagnetischen Transformatorenstapelkerns (2) mit Schichten mit einer amorphen und/oder nanokristallinen Gefügestruktur aus einer Eisenlegierung, wobei der Transformatorenstapelkern (2) zwei parallel zueinander verlaufende Spulenschenkel (3) und zwei mit einander gegenüberliegenden Enden der Spulenschenkel (3) verbundene Joche (4) aufweist. Die Haltevorrichtung (5) weist zwei Halteeinheiten (6, 7), die jeweils derart an einem der beiden Joche (4) anordbar sind, dass die Halteeinheiten (6, 7) an einander gegenüberliegenden Endbereichen des Transformatorenstapelkerns (2) angeordnet sind, und wenigstens ein an den beiden Halteeinheiten (6, 7) angreifendes mechanisches Fixiermittel (8), über das die beiden Halteeinheiten (6, 7) zerstörungsfrei lösbar miteinander verbunden sind, auf. Um einen energieeffizienteren Transformator (1) bereitzustellen, weist die Haltevorrichtung (5) wenigstens einen zwischen den Halteeinheiten (6, 7) eingespannten Abstandhalter (9) und wenigstens ein zwischen wenigstens einer Halteeinheit (6, 7) und dem Transformatorenstapelkern (2) anordbares Federelement auf, wobei die Haltevorrichtung (5) derart ausgebildet ist, dass das Federelement bei an der Haltevorrichtung (5) angeordnetem Transformatorenstapelkern (2) durch einen dabei gegebenen zumindest mittelbaren Kontakt mit dem Transformatorenstapelkern (2) elastisch verformt ist.
Abstract:
An insulated inductor is provided, including at least one coil winding spirally wounded as a plurality of turns, outer surfaces of which are processed by an insulation disposal, each coil winding being provided with two terminal leads respectively at either end thereof. An insulated sealing arrangement of coil windings is also provided, including a system sheet provided with a plurality of through-holes, by which system sheet the inductor is covered and sealed from an exposed side thereof. The invention seeks to provide protection meeting or exceeding requirement of IEC IP54 and UL Type 12, while maintaining electrically insulation and thermal conduction property therefrom.

Abstract:
An apparatus may include an input circuit to receive an AC input voltage having a first magnitude within a range of AC input voltages, and generate a first DC voltage; a boost converter to receive the first DC voltage and output a second DC voltage having a fixed magnitude that is not dependent upon the first magnitude of the AC input voltage; an output circuit to receive the second DC voltage and convert the second DC voltage into welding type power; a control DC-DC converter to receive the first DC voltage and output a control power signal as a third DC voltage; a boost converter control component to receive the control power signal and generate a control signal to control operation of the boost converter; and an auxiliary AC power source to receive the second DC voltage output by the boost converter and to generate an AC auxiliary output voltage.
Abstract:
A nanosecond pulser is disclosed. In some embodiments, the nanosecond pulser may include one or more switch circuits including one or more solid state switches, a transformer, and an output. In some embodiments, the transformer may include a first transformer core, a first primary winding wound at least partially around a portion of the first transformer core, and a secondary winding wound at least partially around a portion of the first transformer core. In some embodiments, each of the one or more switch circuits are coupled with at least a portion of the first primary winding. In some embodiments, the output may be electrically coupled with the secondary winding and outputs electrical pulses having a peak voltage greater than about 1 kilo volt and a rise time of less than 150 nanoseconds or 50 nanoseconds.
Abstract:
The invention relates to a novel inductor, comprising a mounted inner core, electrodes and an outer encasing layer, wherein the mounted inner core comprises an enameled coil and a core shaft, and the mounted inner core and the electrodes are buried into the centre of the outer encasing layer. The novel inductor has the advantages that manufacturability and performances of the inductor can be improved.
