How to cut size, cost without compromising performance, reliability in high-availability power systems
Design How-To  
3/9/2006   Post a comment
The conventional approach to providing high availability in a high power AC/DC power system is to duplicate power supplies on each of two independent AC or DC feeds. That means duplication because it's a proven architecture. An alternative approach is based on using an AC transfer switch. At first sight, this may seem an obvious approach, but the technical challenges of implementing a switch that is fast enough and of sufficient reliability is the challenge. Here's how it can be implemented.

How a constant on-time voltage regulator reduces ripple
Design How-To  
3/6/2006   Post a comment
