Frequently Asked Questions

How does Factorized Power Architecture work?

Factorized Power Architecture (FPA) works by separating power conversion into specialized functions: PRM (Pronto Module) - acts as a voltage regulator providing dynamic bus voltage (typically 48V)

VTM (Voltage Transformation Module) - acts as a current multiplier providing isolated DC-DC conversion with high current output. The PRM optimizes power processing for regulation while the VTM handles voltage transformation and isolation with high efficiency. This separation allows each function to operate at its optimal point, enabling higher overall system efficiency and power density.

Contact our FAE team for FPA design guidance and component selection.

What are the advantages of FPA over traditional power architecture?

FPA advantages over traditional approaches: Higher efficiency - each function optimized independently

Better thermal management - heat sources localized and managed separately

Flexible scaling - add parallel VTM modules for more current

Dynamic voltage positioning - PRM can adjust bus voltage based on load

Reduced distribution losses - high-current conversion happens close to load. Traditional vs FPA for 1000A processor power: Traditional: 48V to 1V in one converter with large distribution current

FPA: 48V to 48V PRM + 48V to 1V VTM at load with lower distribution current.

How do I size PRM and VTM modules for my application?

Sizing FPA modules: PRM selection: Based on total system power requirement

Consider 80% loading for reliability

PRM provides regulation and bus control. VTM selection: Based on load voltage and current requirements

VTMs available for various input/output ratios

Multiple VTMs can parallel for higher current. Example sizing for 1000A at 1V from 48V bus: PRM: P048F4802T512 (5kW module)

VTM: NBM2317 (40A module), need 25 modules for 1000A. Vicor provides online sizing tools and FAE support for system design.

Can I parallel VI Chip modules?

Parallel operation of VI Chip modules: VTM modules support parallel operation for higher current

Use droop current sharing for load balancing

Parallel all units to common input and output buses. PRM modules support parallel operation for higher power

Enable auto-crossover for load sharing

Synchronized turn-on/off for system coordination. Design considerations: Use identical modules from same batch for best matching

Maintain symmetry in bus bar layout

Calculate bus bar requirements for current capacity

Implement proper fusing for fault isolation.

What thermal management is needed for VI Chip modules?

VI Chip thermal management: VTM modules: High power density requires effective thermal management

Integrated thermal pads for direct heatsinking

Water cooling options available for high-power applications. PRM modules: Moderate power density with flexible thermal options

Heatsink or cold plate mounting. Design approach: Calculate power dissipation in each module

Determine heatsink thermal resistance required

Select appropriate cooling method

Consider liquid cooling for high-power systems. Vicor provides thermal models and simulation tools for accurate thermal design.
