Vicor’s VIPAC
™
is an integrated power system leveraging the
latest advances in DC-DC converter technology and modular
front-ends. VIPAC combines application specific power
processing units (PPU), a choice of chassis styles and remotely
located hold up capacitors to provide fast, flexible and highly
reliable power solutions for a wide range of demanding
applications.
The PPU is the core element of the system and may be
specified for 115/230 Vac operation. The PPU incorporates
Vicor’s autoranging FARM modular front-end to provide
transient protection, EMI filtering and inrush current limiting.
The web-based
PowerBench
™
enables designers to configure the
PPU with up to three independently regulated outputs having
power levels from 50 to 500 W and with as much as 900 W
total output power. Vicor’s Maxi, Mini, Micro Family DC-DC
converters, in industry standard quarter, half and full brick
packages, are used to deliver output voltages from 2 to 48 Vdc.
Additionally, the wide trim range of the modules can provide
operating voltages as low as 500 mV.
The PPU is comprised of:
• AC input modular front end
• Vicor’s Maxi, Mini, Micro Family high density
DC-DC converters
• Coldplate or finned chassis
• Choice of output termination styles
The VIPAC is offered in several chassis configurations facilitating
its use in a variety of applications using either conduction,
convection or forced convection cooling. The low profile,
conduction cooled version may be mounted to an existing
cabinet wall, coldplate or heat sink. The 0.5" or 1" finned
versions, available in longitudinal or transverse configurations,
are ideal for use in free or forced convection environments. The
use of standard chassis footprints allows different input voltage
configurations of the VIPAC to be used interchangeably depending
on system and market requirements.
VIPACs use remotely located capacitors to facilitate packaging
and placement options not previously available. The low profile
PPU can be placed closer to the load or attached to cabinet
walls while the capacitors may be integrated into the host system
away from heat sources for improved reliability. System hold up /
ride-thru requirements can also be tailored for specific
applications via different value capacitors. The hold up
capacitors may be obtained from Vicor as a prepackaged hold up
box (HUB). VIPAC is a new class of flexible, high density power
HUB
solutions.
