Optimizing DC-DC converter stability: AC and transient analysis in simulations of source impedance effects
Learn how to optimize DC-DC converter stability through AC analysis in the frequency-domain and transient analysis in the time-domain
Case study: Multi-mode radar
Meeting a short qualification window when upgrading to a VPX power supply
Customer’s challenge
Replacing an older radar with a smaller, lighter, and more capable system meant the need for more power in less space. The advanced surveillance radar required a power supply that could be quickly modified to support multiple generations of radars for high-resolution imaging, target tracking, and submarine periscope detection in all weather conditions.
- Modular power supply that can be quickly modified to support new requirements
- Reduce time to market and engineering effort
- Meet specific user-defined output voltage requirements
The Vicor solution
Vicor VPX power supplies are based on high performance power modules and efficiently deliver the power and voltages required within the standard footprint. The VPX power supplies are configurable, rugged, and can be easily modified and adapted to new requirements for quick prototyping. Scalable and adaptable to provide a form factor that easily upgradeable in the future.

Power delivery network
The Vicor VITA 62-compliant 3U power supply is based on Vicor DCM™ DC-DC converter
technology, which provides superior density in a low-profile package. This solution can
provide up to 600W within the 3U package. Employing high efficiency, two-sided conduction-
cooled modules, the Vicor VITA 62 power supply meets the 85°C operational temperature (at
the card edge) while powering the downstream loads.
