 PRODUCT INTELLIGENCE, 21 Feb. 2012.There’s one thing all electronics need, and that’s power electronics. Military power supplies and converters are important parts of the system they inhabit, and as such need to meet rigorous standards lest the entire system shut down for want, or excess, of power. Systems integrators who are looking to purchase power supplies and converters need to weigh reliability, weight, power and cost carefully.
“Military and avionics customers are continually seeking smaller size, lower weight, and higher efficiency in their power supplies to save on board space, design cost, and operation cost,” says Steve Butler, vice president of engineering at VPT Inc. in Blacksburg, Va. Not only are power supplies being weighed against those factors, but as a vital piece of any system they must be rugged and reliable.
