Maybe I've been working on space systems too long...you can draw your own conclusions about that. At any rate, even though it isn't likely to be what Derek was after in the first place, let me try to make my statement clearer: What I was referring to was the distinction between a power converter (e.g., dc-dc converter) for a single LRU in a large system, in contrast to a unit that is a power supply (like a DDCU on the space station) that is converting power from an unregulated source (let's say a solar panel) and providing regulated power to a number of units on a power bus. The former would typically have a much more stringent output ripple requirement (as indicated by Robert Macy) than the latter. DB
