How Do You Decide the Best Power Chain for Your Application?

How Do You Decide the Best Power Chain for Your Application?

The Power Component Design Methodology is an extremely flexible approach to the development of power systems, using power components to produce designs that are optimized for your application. But how can you determine what is the “optimum” solution to your particular design challenge? Consider the following five figures of merit: Highest Operating Efficiency Lowest Component Count Lowest Cost Smallest Footprint Best Fit The demands of the application will determine the figure of merit that is most appropriate. For example Highest Operating Efficiency (the highest overall efficiency of the complete system at its maximum operating...

Communications Applications No Longer Need Isolated Bus Converters

Communications Applications No Longer Need Isolated Bus Converters

Communications infrastructure equipment has traditionally used lead-acid batteries as a backup supply, which requires the batteries to power a positive referenced 48 V distribution system to avoid corrosion (cathodic protection). As this -48 V supply is used to power +48 V electronics, isolation between the batteries and the communication electronics is required. So the use of isolated bus converters became standard practice in these applications. With modern communications systems merging with server technology, and the communication portion moving from electrical to optical systems, today’s equipment can use negative referenced+48 V backup, meaning isolation is...

Flexible Fault Management

Flexible Fault Management

The Factorized Power Architecture (using the PRM and VTM) provides an efficient means of providing power under rapidly varying load conditions. In the event of a fault, the VTM module shuts down automatically and remains shut down until restarted by the PRM module. The addition of a Fault Management Circuit allows for much more flexibility in the response to a fault. The Fault Management Circuit described here can be used for a PRM driving one or two VTMs in series or parallel. The circuit is compatible with the PRM / VTM families that support...

White Paper Describes How Eliminating Isolation Improves Performance of 48 V Power Systems

White Paper Describes How Eliminating Isolation Improves Performance of 48 V Power Systems

The telecommunications industry has traditionally used positive-referenced DC power distribution to reduce the chance of copper wiring corroding. Modern systems, however, often use active cathodic protection, eliminating the need for a positive-referenced power system.
