Summary
This case study outlines the challenges and solutions associated with the power delivery network for tethered unmanned vehicles, specifically focusing on the Vicor solution. The document details how high-voltage tether transmission ranging from 500V to 800V allows for extended tether lengths and reduced cabling size, enabling drones to operate at greater altitudes or travel longer distances underwater. Key objectives include optimizing power delivery through the tether, ensuring high reliability with a rugged power supply, and converting high voltage to a safe 48V SELV. The study presents the BCM4414 module, which provides efficient power conversion with over 97% efficiency, facilitating the step-up and step-down processes necessary for tethered operations. The advantages highlighted include reduced tether size and weight, lightweight conversion capabilities, and modular design that accommodates various design requirements. Overall, the findings illustrate a more flexible and capable system that enhances operational efficiency for tethered aerial and underwater vehicles.
