Efficient power conversion technology now makes buoy systems practical for powering real-world devices. Autonomous offshore power systems (AOPS) now capture mechanical wave energy and convert it into usable power for a wide range of oceanic applications such as offshore oil and gas exploration and production, offshore carbon sequestration, oceanographic research, aquaculture and homeland defense. An […]

Super-efficient power converters help hovering drones take flight
When the task calls for a aerial system that can hover in place, the often-chosen approach is to employ a tethered drone. A tethered drone, generally a multirotor, gets its power and communications signals via a flexible wire or cable. Where battery powered multirotor drones can exhaust their batteries in 20 minutes or so, tethered […]
How to design modular dc-dc systems with modules, Part 5: Load considerations
The previous tutorials in this series addressed the appropriate filtering, stability, and protection concerns for power modules when used as elements of a complete DC-DC power system. This tutorial is focused on the load-specific aspects of a system designed with power modules. It was once possible to conceptualize the load supplied by a DC-DC module […]
VITA 62 compliant power supplies for MIL-COTS VPX applications
Vicor Power Systems’ new line of VITA 62 compliant power supplies are designed for 3U Open VPX systems and achieve high-efficiency and high-power density in a rugged, conduction-cooled chassis. The initial products operate from a nominal 28V or 270V DC input, with predefined output voltages ranging from 3.3V to 12V, delivering up to 600W of […]
