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: Aircraft radar
High reliability VITA 62 supply that handles unique current requirements
Customer’s challenge
Aircraft radar systems have unique power and current requirements driven by the need for high-peak power, rapid scanning, and strict environmental constraints (weight, space, and altitude). Modern airborne radars require sophisticated power management to handle rapid, high-current pulses for transmitter modules while operating within the stringent limits of aircraft electrical systems.
- Need a high reliable power converter used in harsh conditions
- Meet the power and current requirements
- Reduce time to market
The Vicor solution
Vicor VITA 62 power supplies are based on Vicor high performance Vicor DC-DC converter technology. The high power and current delivery, strong thermal performance, and reliability of Vicor VPX products ensure longer mission times and superior system endurance to support crucial missions.

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 converter meets the 85°C operational temperature (at the
card edge) while powering the downstream loads.
