International Classification:
H05K 336
US Classification:
29830, 29840, 29842, 29843
Abstract:
A method for assembling a multi-deck power supply device including control and power components. The method comprises providing a first circuit board having a first and a second side. Two prefabricated pin holders are positioned on the first side of the first circuit board. Each pin holder includes two threaded inserts, a set of first pins and a set of second pins. The first pins are floating for self-alignment during soldering. After the first pins are soldered on the first side of the first circuit board, a second circuit board is aligned above the first circuit board, and the first and second pins are soldered to the second circuit board. The first pins may include pre-assembled oscillation dampers, such as magnetic material beads.

Current Limit Circuit And Power Supply Including Same

View page
US Patent:
7254044, Aug 7, 2007
Filed:
Jan 11, 2005
Appl. No.:
11/033187
Inventors:
Marty Perry - Tucson AZ, US
Ian Poynton - Marana AZ, US
Assignee:
Artesyn Technologies, Inc. - Boca Raton FL
International Classification:
H02M 3/335
US Classification:
363 20, 363 89, 323299
Abstract:
The present invention is directed generally to a power supply. According to various embodiments, the power supply includes at least one DC/DC converter. The converter includes a primary switch controlled by a pulse width modulated control signal such that the primary switch is on for a D time period of each switching cycle of the converter and is off for a 1-D time period of each switching cycle. Also, the power supply includes a current sensing element connected in series with the primary switch. In addition, the power supply includes a current limit circuit connected to the current sensing element. The current limit circuit includes a functional circuit having a first input responsive to a first signal whose voltage is proportional to the output current of the converter during the D time period of the switching cycle of the converter. A second input of the functional circuit is responsive to a second signal whose voltage is proportional to the output current of the converter during the 1-D time period of the switching cycle of the converter. In that way, the voltage of the output signal of the functional circuit is proportional to the output inductor current of the converter over both the energy storage phase (the D interval) and the energy deliver phase (the 1-D) interval of the converter.

Printed Circuit Board And Device Including Same

US Patent:
7256676, Aug 14, 2007
Filed:
Sep 16, 2005
Appl. No.:
11/228831
Inventors:
Ian Poynton - Marana AZ, US
Assignee:
Artesyn Technologies, Inc. - Boca Raton FL
International Classification:
H01F 5/00
H01F 7/06
US Classification:
336200, 336223, 336232, 296021
Abstract:
A multi-layer printed circuit board. The multi-layer printed circuit board includes a first winding, and a first via connected to the first winding. The first winding includes a first edge. The first edge defines a first footprint. The first footprint surrounds and is proximate an opening defined by the printed circuit board. At least a portion of the first via is between the first footprint and the opening.

Packaging Method For Very High Density Converters

View page
US Patent:
20160359426, Dec 8, 2016
Filed:
Dec 11, 2014
Appl. No.:
15/103617
Inventors:
- Tucson AZ, US
Ian Poynton - Marana AZ, US
Enrique Velasco - Marana AZ, US
Assignee:
Rompower Energy Systems, Inc. - Tucson AZ
International Classification:
H02M 7/00
H02M 7/21
H05K 1/14
H05K 1/02
H05K 9/00
H05K 1/18
Abstract:
Meeting todays requirement in power supply technology demands significant technological advancement in optimizing circuit topology, components and materials, thermal and packaging designs. These requirements are being pushed mainly by continuously increasing power density and efficiency requirements. Ultimately, these trends will come to a point whereby limitations from the above mentioned technological advancements is dependent on one of the above, which is the packaging design. To realize this dependence, we need to look at the growing power systems for modern equipment out there. Let us enumerate some of the available AC adapters in terms of power densities of a 45 W adapter. Firstly, square type architecture introduced by Apple is about 7 W/in3, considering the packaging has a profile limitation whereby its AC plug is removable thus occupying relatively bigger chunk of the volume. The next one is by Asus of similar profile to Apple incorporating the AC Plug eliminating the socket assembly in the packaging; which packs about 9 W/in3. Lastly, the typical rectangular profile by Eos which is about 7 W/in3. As for this particular embodiment it is about 40% smaller in profile, in contrast to the 45 W Apple packaging, with increase power density of about 12 W/in3. Packaging design method plays a great role in achieving the above requirements for a very high density converters.

Resonant Transition Controlled Flyback

View page
US Patent:
20140334194, Nov 13, 2014
Filed:
May 9, 2014
Appl. No.:
14/274598
Inventors:
Marco Davila - Tucson AZ, US
Ian Poynton - Tucson AZ, US
International Classification:
H02M 3/335
US Classification:
363 2102
Abstract:
A new and useful method and inductive circuit is provided that provides a resonant transition control that involves shorting the winding of an inductor or transformer to delay the natural ringing transition. The present invention provides for controlling the natural ring of an inductive circuit has a choke that stores and releases energy, a switch device having a closed state in which it causes the choke to store energy and another switch device having a closed state in which it causes the choke to release energy. The inductive circuit is configured with parasitic capacitance that would normally produce natural ringing when energy in the choke has been substantially released. The invention is characterized in that it provides for shorting the choke to trap and hold current and pause the natural ringing until power is directed to the inductive circuit to release shorting of the choke and initiate storage of energy in the choke.
