New Article: Complex Factors Drive Mil/Aero DC/DC Converter Choice

December 4, 2012 — Read our latest technical article on choosing the correct level of DC-DC converters in COTS Journal today.  Or, you can download the entire whitepaper on this topic here.

Synopsis:

Complex Factors Drive Mil/Aero DC/DC Converter Choice

Matching the proper DC/DC conversion technology with a military / aerospace design is less straightforward than may seem. A host of reliability, packaging and standards issues need to be considered.

Critical applications range from undersea to military ground to commercial and military avionics to deep space. DC/DC converters, point of load converters, EMI filters and other power modules are offered by various manufacturers, all claiming high reliability. The question is, how do you know what level of quality and reliability you are getting, and how do you select the correct level for your application?

VPT Adds 15 Amp Point of Load DC-DC Converter to Space Family of Power Conversion Products

VPT is the only manufacturer to now offer two point of load converters that are MIL-PRF-38534 Class H and Class K Qualified, 100K rad hard, and available off-the-shelf.

BLACKSBURG, VA, May 8, 2012 – VPT Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI), announced today the availability
of a new point of load power converter designed and manufactured for use in the extreme environment of space. The new SVGA0515 Series point of load DC-DC converter is now qualified to MIL-PRF-38534 Class H and Class K by the Defense Logistics Agency.  The SVGA delivers up to 50W of output power, is radiation hardened to 100 krads (Si) including Enhanced Low Dose Rate Sensitivity (ELDRS), and is characterized to SEE of 85 MeV-cm2/mg.

The SVGA Series is the latest addition to VPT’s existing line of space DC-DC converters. The SVGA functions as a non-isolated,
regulated buck converter that steps down the voltage at the point of use in a distributed power system. From a single, small size, high current package, this module saves significant board space, weight, and cost for power systems headed for LEO, MEO, GEO, and deep space missions.

“To reduce weight and component cost, distributed power systems are relying more on smaller, less expensive point of load
converters used in conjunction with the larger, traditional, isolated DC-DC converters. Customer response to our space-qualified, off-the-shelf, point of load DC-DC converters has been phenomenal,” explained Monty Pyle, Executive Director of Sales. “We’ve been asked for a higher current option without the need to waste space and weight stringing together multiple POL converters.
We’re proud to announce that this product will satisfy the needs of space customers requiring higher power levels and stringent radiation requirements.”

Russian Space Research Institute Thanks VPT

VPT recently received a letter from the Russian Space Research Institute recognizing VPT’s contribution to the development of the Lunar Exploration Neutron Detector (LEND) for NASA’s Lunar Reconnaissance Orbiter (LRO), launched in 2009.

In a letter, the Institute said, “Due to perfect cooperation with your company, the flight-quality secondary power converters made by VPT were delivered to us in the shortest terms possible at our special request and then they were successfully and timely integrated into the instrument having passed all the testing procedures.”

The letter went on to praise VPT with “Since the start of the LRO mission on June 19, 2009, the LEND instrument has been successfully operating as part of the Lunar Reconnaissance Orbiter which proves high technical performance and reliability of your company’s products.”

The LEND instrument provided a unique dataset on hydrogen abundance in the lunar soil, and this data is already used by the scientific community worldwide to plan further manned missions to the Moon.

VPT Featured in Article on Radiation Hardened Electronics

In the June issue of Military and Aerospace Electronics Magazine, VPT’s team provides technical information and market insight for John McHale’s article “Radiation-Hardened Electronics Technology Remains Stable Amid Steady Demand in the Space Market.”

Excerpt:
“The hottest market shift is a huge demand for rad-hard point-of-load converters that can be used in conjunction with traditional isolated rad-hard DC-DC converters to support high efficiency distributed architectures,” says Daniel Sable, president, of VPT Inc. in Everett, Wash. “Using point-of-load converters instead of standard DC-DC converters throughout a system saves size, weight, and dramatically improves efficiency and therefore thermal designs are simplified. All of these are critical issues for spacecraft. This technology is very mature for commercial applications, but there have been few offerings of high efficiency, non-isolated, rad-hard point-of-load DC-DC converters for use in space applications.”

“A major industry concern the past few years has been enhanced low dose rate sensitivity (ELDRS), says Leonard Leslie, manager, space programs at VPT. Designs must not show ELDRS, which is “caused by components degrading earlier when exposed to a dose rate closer to that seen in the application, as opposed to the high dose rates traditionally used for design qualification,” he adds.
