The challenge of efficiency in embedded power electronics

Embedded processors are smaller, more powerful, and more power- efficient than ever before, and that is expected to continue. While this is good news for increased capabilities of embedded systems, it can put power supply companies in a bind.

These efficient processors, although they operate at decreased voltages, still demand increasing amounts of electric current to perform a growing number of tasks. This demand for increased current and decreased voltage puts power supply efficiency in the cross hairs.

"In a lot of these applications they need more power because they want to do more things; this calls for higher current," says Tom Curatolo, director of global defense and aerospace business at Vicor Corp. in Andover, Mass.

"The problem is now your current requirements on your load is going up substantially," which can compromise device efficiency," says Monty Pyle, vice president of sales and marketing at VPT Inc. in Blacksburg, Va.

The design challenges to today's embedded systems power supply companies do not end there. As it is for so many aspects of electronics today, systems designers are demanding the highest level possible of small size, weight, power consumption, and cost (SWaP-C).

"Size, weight, and reliability are very critical," points out Dennis Kelemen, administrator of the power supply division of Pico Electronics Inc. in Pelham, N.Y.

"The only thing that doesn't go up is the size of the platform," says Christophe Massenet, vice president of business development for the U.S. operations of Gaia Converter in Bordeaux, France. "Our equipment needs to be smaller, and the power density needs to go up."
