US Patent:

7474185, Jan 6, 2009

Filed:

Jul 8, 2005

Appl. No.:

11/177777

Inventors:

Roger Hooey - Rockwall TX, US
Drue Nicholson - Rockwall TX, US

Assignee:

NetPower Technologies, Inc. - Richardson TX

International Classification:

H01F 27/08

US Classification:

336 55

Abstract:

A high-density power converter that benefits from improved packaging techniques and thermal handling capability is provided. The power converter includes a magnetic core. The converter further includes a printed circuit board providing at least one cutout for receiving a portion of the magnetic core. A circuit is magnetically coupled to the magnetic core. A stopper is configured at an edge of the cutout proximate to the circuit to hold the magnetic core at a predefined distance relative to the circuit, thereby meeting a safety distance requirement between the core and the circuit. Advanced thermal management is provided by way of a heat sink assembly to enhance the thermal-handling capability of the converter.
