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