Design Considerations
Factorized Power Architecture
PRM modules must be used in conjunction with VTMs to form a complete power solution. The PRM provides regulation and power factor correction, while the VTM provides current multiplication and isolation. The output of the PRM connects to the input of the VTM for the complete FPA solution.
Automotive Environment
PRM Automotive modules are qualified for automotive temperature ranges (-40°C to +105°C) and tested for vibration, shock, and EMC compliance. Design must ensure proper derating in high-temperature environments to maintain reliability.
System Integration
PRM Automotive modules excel in applications where you need regulated power with high efficiency and automotive qualification. They are ideal for FPA systems in automotive environments.
Frequently Asked Questions
What is Factorized Power Architecture (FPA)?
FPA is Vicor's approach to power system design that separates regulation from current multiplication using PRM and VTM modules. This allows optimization of each function independently, resulting in higher efficiency, power density, and performance.
What does AEC-Q100 qualification mean?
AEC-Q100 is an industry-standard qualification for integrated circuits in automotive applications. It includes tests for temperature, humidity, vibration, and electromagnetic compatibility.
How do PRM and VTM modules work together?
The PRM provides regulation and power factor correction, while the VTM provides current multiplication and isolation. The PRM output connects to the VTM input to create a complete regulated, isolated power solution.
