Power Delivery Solutions for Unmanned Aircraft

This case study focuses on the challenges faced by unmanned aerial vehicles (UAVs) that operate on solar power, particularly in achieving long flight durations. The document outlines the solution provided by Vicor, which incorporates maximum power-point tracking (MPPT) circuitry to efficiently convert solar energy into a usable voltage for battery charging and power system integration. Key objectives include efficient high voltage to SELV conversion, a compact design for lightness, and a robust solution for reliability. The study details the importance of high-efficiency power-conversion technologies such as Zero-Voltage Switching and Zero-Current Switching, which are essential for enhancing the capabilities of UAVs. Additionally, it describes the power delivery network established through Vicor's BCM6123 and PI3741 ZVS Buck-Boost regulator, highlighting their specifications and efficiencies that support various UAV loads. The findings demonstrate the enhanced performance and operational capacity achieved through these innovative power solutions.
