Tethered UAV Intelligent Reel for Tethered, aerial/ underwater vehicles
February 16, 2022
This class of unmanned vehicle is powered and controlled via a tether from a ground-based power source. High-voltage tether transmission of 500V to 800V allows for greater tether lengths and smaller cabling, enabling the drone to fly higher or travel longer distances underwater. The power delivery network (PDN) inside the vehicle must be capable of down-converting the tether’s high voltage with high efficiency and power density to not take up important payload space. Tethered drone applications typically require a 1 – 5kW ground power supply tethered to a rotor-wing UAV or UUV, and offer unlimited run time and greater control.
