• Power Components Simplify 1kW Power Design

  (7 pages, 368k)
  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.

• Current Share Board

  (2 pages, 35k)
  "Current sharing" also known as load sharing, is the ability to divide the output current evenly across all active power supplies. This greatly reduces stresses on each power supply and allows them to run cooler resulting in higher reliability. Standard current sharing techniques typically utilize shunt resistors or Hall-Effect devices to . measure the current from each power supply. Power shunt resistors continually dissipate power and require cooling . especially when dealing with high output currents of >100 Amps.

• Adjustable Latching Output Over Current Circuit

  (4 pages, 245k)
  Many users, for logistical reasons, employ a particular module for many applications at significantly lower power than the unit is able to provide. The potential damage to down stream PCB traces and components caused by the module high current source capability creates a need for an adjustable latching output current limit circuit.

• Controlling the BatMod with a Digital Potentiometer

  (2 pages, 36k)
  The BatMod is a modular, component level DC-DC converter that provides a programmable output voltage and current limit suitable for battery charging or other applications that require constant current with external control.

• Designing a Battery Charger

  (2 pages, 28k)
  Vicor's BatMod current source module enables designers to easily build a compact, lightweight battery charging system with commonly available parts.

• Creating High Voltage Outputs

  (1 page, 40k)
  This Applications Note describes two approaches to producing a high voltage output. One solution provides a fixed output voltage, the other an adjustable output voltage.

• Designing a Power Supply with Multiple Input Options

  (1 page, 24k)
  Some electronic systems such as field communications equipment must be able to operate from a variety of power sources. These systems may also require backup power in case the primary source is interrupted.

• Powering Dynamic Loads

  (2 pages, 32k)
  This document illustrates Vicor converters' current limiting safety feature and design strategies that will allow your power system to maintain stable output voltages and sufficient available power levels in applications with widely and / or rapidly fluctuating loads.

• Soldering Methods and Procedures for RoHS Compliant Modules
