Dave Berry Explains Power Averaging on PowerElectronics.com

Power ElectronicsModern loads are highly dynamic. It’s no longer the case that power systems simply deliver a constant power output; in applications ranging from pulsed amplifiers to flashing LEDs, power system developers must now support loads that draw power in short bursts.

This presents a challenge as traditional converters are specified to deliver a maximum output power and current.  This makes the power system heavier, more expensive and larger because it needs to be designed around the maximum output current.

In his article featured on powerelectronics.com, Power Averaging to Save Weight, Cost, and Space, Dave Berry, a member of our applications engineer team, explains how some modern power components, such as the DCM, can deliver bursts of higher output current than would be suggested by their rated output power. In the article, he shows a test system with a peak output of 960 W from a DCM rated at 320 W.

This concept of power averaging enables power developers to create systems that are lighter, smaller and lower cost than would be the case with a traditional approach. Read Dave Berry’s article to learn more about how you could use power averaging to improve your next design.
