Applications Push Input Voltages of DC-DC Converters Higher

Applications Push Input Voltages of DC-DC Converters Higher

With power consumption and the cost of power increasing exponentially, datacenters are rapidly migrating toward high voltage DC power distribution because of their increasing need to reduce power distribution losses and improve overall system efficiency.

48 Vdc Distribution; a Safe, Practical and Efficient Solution for Equipment Racks

Vicor’s new AC Front End Module has an isolated, regulated output of 330 W at 48 Vdc. Its applications are many and varied, including powering rack-mounted equipment in telecommunications or data centres. However designers for such applications sometimes ask why the DC output has been set at 48 V rather than 12 V, or even 5 V?

400V DC Power Distribution Improves Efficiency for Telecom and Datacom Applications

With telecom and datacenters becoming ever more important to our work and leisure activities, the demand placed upon these applications is increasing dramatically. Every percentage-point increase in efficiency results in significant cash saving for the operator – and hopefully, the customer – in the cost of wasted power.

What to Consider when Choosing a Buck Regulator

In our previous post, an interview with Robert Gendron, VP, Strategic Marketing and Business Development for Picor, we asked, What is a Buck Regulator? In this second in the series, we look at how to choose the product that is right for your design.

Why Optimize Buck Regulators for 8V-18V Operation?

Why Optimize Buck Regulators for 8V-18V Operation?

Over the past few months, I have published a few articles discussing the advantages of our soft turn on ZVS Buck topology when it is applied to a wide ranging (8V-36V) input voltage combined with large step down ratios of as much as 36:1.

Fast, Online Simulations Shape Advanced Power Supply Architectures

The task of the power system engineer grows steadily more complex. At the level of individual PCBs, semiconductor devices – microprocessors, FPGAs and the like – demand a range of discrete voltage levels, frequently at around 1 V and at currents of tens of Amps. The physics of distributing power at these levels mandates regulation as close to the point-of-load as possible: I2R losses and minute but inescapable inductances are always poised to degrade the performance of low-voltage, high-current paths that see rapid step-changes in power demand. At the other end of the power-conversion...
