Designing VME Power Systems from Standard Modules
With each new military system design system design come the same challenges: more processing power, tighter specs, and shorter development time. Continual advances in system performance often require similar advances in the power system. VME architecture is common in many military applications, and can be readily built around standard or custom circuit cards…

Deploying a Distributed Power Architecture with Point of Load DC-DC Converters
Today's commercial avionics, military and space power electronics need higher performance while decreasing size, weight and cost. One way to decrease the power footprint is to move to a distributed power architecture that uses point of load converters, which offer the advantages of smaller size, higher efficiency, and better performance than the isolated power converter method.
