Tethered UAV | Datasheet Preview

Vicor’s BCM line of high-efficiency bus converter modules along with the zero-voltage switching (ZVS) buck regulators can form the backbone to support high-voltage UAV tether transmission. The 500V to 800V transmission allows for greater tether lengths and smaller cabling, allowing drones to fly higher or travel longer distances underwater. BCMs such as the BCM4414 can be used in a UAV’s power delivery network to downconvert the tether’s high voltage with a high efficiency and power density in order to save on important payload space. The zero-voltage switching buck regulators offer board-level designers maximum power density and flexibility for high-efficiency point-of-load DC-to-DC regulation. ZVS regulators are highly integrated with control circuitry, power semiconductors, and support components in a high-density LGA, BGA, and system-in package.
