Vicor Power Systems communications and computing applications

Server docking station shelf power

Key challenges

  • Develop a very small low profile power supply that accepts universal AC and provides a 5VDC output @ 750W in a air-cooled configuration

Server docking station shelf power

Solution

  • Provided a solution using two PFM AC front ends along with PRM regulators and VTM current multipliers to meet the requirements
  • Supported small footprint of approximately 14 x 3.5 x 2in

RF transmitter

Key challenges

  • Develop a very small low profile power supply that accepts 28VDC input and converts down to four outputs of 4V, 6V, -5V, and 18V
  • Featured solution needs to be highly efficient at full load
  • Configuration needs to be conduction cooled

RF transmitter

Solution

  • Solved weight and sized concerns using half-chip PRM regulators and half-chip VTM current multipliers
  • Featured high efficiency of >92% at full load

Outdoor satellite transceiver

Key challenges

  • Develop a very small high-efficient power supply with multi DC outputs and very low ripple
  • Power supply needs to have a maximum power of 150W
  • Required to be conduction cooled

RF transmitter

Solution

  • The use of half-size PRMs and VTMs allowed for the required outputs and high efficiency in the small available volume
