US Patent:

20160128235, May 5, 2016

Filed:

Oct 31, 2014

Appl. No.:

14/530014

Inventors:

- Waltham MA, US
Stephen R. Elkins - Franklin MA, US
Bradley S. Jaworski - Bedford MA, US

International Classification:

H05K 7/20
H05K 13/04

Abstract:

A power converter magnetics assembly is disclosed. The power converter magnetics assembly can include an interface panel, a magnetic component mounted to the interface panel to form a magnetics subassembly, and a chassis coupled to the magnetics subassembly. The chassis can have a cavity with an opening. The magnetic component can be received within the cavity and the interface panel can be disposed over the opening and secured to the chassis to form an enclosure about the magnetic component.

International Classification:

H01F 19/04
H01F 41/04
H01F 27/28

US Classification:

336 73, 29605, 29857

Abstract:

A magnetic assembly to receive current having a high current and high frequency includes a transformer, at least one resonant inductor, and at least one auxiliary inductor. The resonant inductor is in electrical communication with the transformer, and the auxiliary inductor is in electrical communication with the resonant inductor. The magnetic assembly further includes at least one conductor having a first end coupled to the auxiliary inductor and a second end coupled to the transformer. The conductor extends continuously between the first and second ends without terminating to form an auxiliary winding of the auxiliary inductor, a resonant winding of the resonant inductor, and at least one primary winding of the transformer.

International Classification:

H01F 27/10
H01F 41/06

US Classification:

336 60, 29605

Abstract:

An apparatus includes a coil assembly, a core, and at least one cooling channel. The coil assembly includes at least one winding configured to receive a varying electrical current. The core includes multiple segments, and the at least one winding is wound around portions of the segments and is configured to generate a magnetic flux. The at least one cooling channel is configured to transport coolant through the coil assembly or core in order to cool the coil assembly or core. Portions of the segments of the core can be separated from one another to form multiple cooling channels through the core, and the multiple cooling channels can be configured to transport coolant through the core. The coil assembly may include at least one insulative spacer having multiple cooling channels, and the multiple cooling channels may be configured to transport coolant through the coil assembly.
