客户所面临的挑战

Effective surveillance requires uninterrupted sensing and communication to ensure the safety and security of valued property, equipment, and assets. UAVs are used to surveille wide areas that may be hard to reach or when those spaces are not in a fixed location. The best surveillance UAVs stay in the air for as long as possible and are equipped with high-resolution cameras, thermal imaging sensors and communication links. The key goals were:

Increase flight time
Support power-hungry functions without adding size and weight
High-efficiency and simplified thermals

Vicor 解决方案

A surveillance drone must maximize productivity while also being able to carry high-performance cameras and sensors. Vicor high-density power modules support all these power-hungry functions without adding unnecessary size and weight to the UAV, extending flight time allowing for more functionality. Key benefits were:

主要优势

DCM best-in-class power density

High efficiency extends flight time

Keeps backup battery charged

供电网络

Power dense Vicor DCM™ DC-DC converter modules are ideal for surveillance UAVs. They convert the 48V battery to a manageable voltage that can be matched to the UAV system loads using compact Zero-Voltage Switching (ZVS) buck and buck-boost regulators. The DCM converter modules can also keep the UAV backup battery charged to ensure safety through redundancy.
