Applications
PRM Aerospace modules are optimized for aerospace and defense applications requiring regulated power conversion with high reliability. Common applications include:
Satellite Power Systems
Regulated power supplies for satellite systems with radiation tolerance and extreme temperature operation.
Avionics Power
Regulated power supplies for aircraft avionics systems requiring high reliability and environmental qualification.
Space Exploration Equipment

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.
Extreme Environment Operation
PRM Aerospace modules are designed for extreme temperature ranges (-55°C to +125°C) and tested for vibration, shock, and radiation exposure. Design must account for derating in extreme conditions to maintain reliability and performance.
Radiation Effects
For space applications, consider total ionizing dose (TID) and single event effects (SEE) impacts. Radiation hardened options are available to ensure continued operation in high-radiation 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 radiation tolerance options are available?
PRM Aerospace modules are available with radiation hardened options providing protection against total ionizing dose (TID) and single event effects (SEE) for space applications.
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.
