Join us for a brief tutorial on working with the flexible DVPL Series point-of-load DC-DC converters. Usage of the track pin and sequencing functions are detailed in a whiteboard discussion and lab demonstration. 

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.

BLACKSBURG, VA, June 1, 2010 – VPT, Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI), has introduced a new EMI (electromagnetic interference) filter module for distributed power systems. The new VPTc10-28 EMI filter satisfies strict reliability requirements for commercial avionics and military systems in the U.S. and Europe.

The VPTc10-28 Series EMI filter and transient suppressor combines two modules in one space-saving package. This module reduces the reflected noise of DC-DC converters while simultaneously protecting a power system from inrush current damage and reverse polarity conditions.  

In the May issue of Military Aerospace Magazine, Courtney Howard includes comments and insights from VPT in her article, "Power is Paramount."

Excerpt:

"We continue to see the influence of lower-voltage processors driving our customer base, which includes a broad base of worldwide designers in the high-reliability avionics, military, and space markets, to develop power conversion designs that are extremely efficient, of a small size, and cost effective," notes Michael J. Bosmann, senior vice president of sales and marketing at VPT Inc. in Everett, Wash.  

"A company needs to remain flexible in its approach to serving the power conversion electronics needs for the mil-aero applications of the future," advises Bosmann. "Our research and development in process technology is focused on improving performance and reducing cost, whether in material, process time, or both. The one constant in this market, however, is always high reliability. Improving reliability is paramount to everything we've done in the past and will do in the future."

VPT recently donated $15,000 to the Virginia Tech Electrical and Computer Engineering (VT ECE) Department. In the photo, VPT’s President Dr. Dan Sable presents the donation to Professor Scott Bailey in the Virginia Tech University Laboratory for Remote Sensing and Aeronomy. 

Pictured behind the check is a space telescope that is part of the NASA Polar NOx sounding rocket mission for which Professor Bailey is the principal investigator. This mission will be powered by VPT's standard product DC-DC converters and is scheduled for launch in February 2011. The Polar NOx mission will measure nitric oxide, thought to be a significant source of ozone destruction, in the upper atmosphere. 

Dr. Dan Sable will continue his lifelong work in the space arena with a presentation on radiation hardened DC-DC converters at the upcoming Space Parts Working Group conference, May 5, in Torrance, California.

BLACKSBURG, VA, April 13, 2010 - VPT Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI), today announced that several new modules are available for the DVFL, DVTR, and DVHFSeries DC-DC power converter product lines.
