Power Components Simplify 1kW Power Design

June 04, 2012 // By Jeff Ham, Vicor
Not long ago, designing a 1,000 W power supply for operation on worldwide AC lines was a task for the most experienced power design engineers. Besides dealing with the design of autoranging front-end rectification circuitry and isolated power conversion stages, the designer faced a myriad of other complex technical and design issues: inrush current limiting, sizing and selection of holdup capacitors, transient protection, thermal design, and worldwide safety agency and conducted noise requirements.
