Overcoming Tethered UAV Challenges with a High-Voltage, Compact Module-based Power Delivery Network

Robotic and unmanned vehicle (UV) fleets are reshaping the future of automation and production. Continuous improvements in productivity are being driven by extended range and increased uptime that are reliant on fleet maintenance, particularly the charging process. One of the top costs and inefficiencies today is the need for human intervention in the charging process; therefore, UAV and automated robotics developers are looking for ways to make further improvements in power density and efficiency to lighten loads and extend battery life. Realizing such improvements requires reconsideration of the power delivery network (PDN) and the use of high-density power modules instead of traditional, all-in-one power supplies

A growth markets for UAVs is tethered drones with extended uptimes and increased load capabilities for applications such as surveillance and communications. Ispagro addresses this market in an innovative way by retrofitting existing, market leading small drones from manufacturers such as DJI and Parrot. Retrofitting existing UAVs allows Ispagro to rapidly address evolving market needs in a cost-competitive manner, however, these battery operated, small drones have limited payloads and uptimes. Adding a tether extends uptime and provides fail-safe operation for safe landing via on-board battery in case of power failure, tether, damage, etc. The tether, however, does add more challenges for the UAV designer who must accommodate the 50m tether cable and aerial units within a tight 400 gm payload limit.

Ispagro overcomes this challenge by utilizing a PDN with Vicor BCM fixed-ratio DC-to-DC converter power modules to deliver efficient, reliable power to the airborne UAV via the tether
