High-density, high-power modules enable lighter, safer, lower cost tether cables to extend missions
This class of unmanned vehicle is powered and controlled via a tether from a ground-based power source assisting in extended missions
お客様の課題
Inspection UAVs ensure that infrastructure is sound, safe, and functional. These UAVs must be able to be easily maneuvered and nimbly access hard- to-reach spaces to inspect vast terrains. To succeed in their mission, they must also operate reliably in harsh environments and withstand electrical interference from power lines and other high-energy sources. The key goals were:
- Improve reliability of energy transmission by moving to a contactless power solution
- Compensate for variations in distance between the inductive transmitter and receiver
- Minimize inertia, and thus the power required to drive the gantry, by reducing weight and size
Vicorソリューション
The gantry’s inductive pick-up generated a widely varying AC output that was rectified and then regulated by a Vicor DCM DC-DC converter. These converters are able to operate over a very wide input voltage range of up to 9 to 1 (high to low input range). This capability enabled the reliable, regulated supply needed for the gantry robot motor drives, actuators and control system.
主な利点
主な利点
High-power density to enable smaller form factor and lower weight
Very low weight (29g)
Small size (just 47.7 x 22.8 x 7.2mm)
Vicor DCM converter’s wide-input range simplifies design
The DCM converter regulated and isolated the widely varying output from the inductive pick-up, providing a stable output. In addition, the converter’s double-sided cooling reduced the operating temperature, providing increased reliability. To analyze this power chain go to the Vicor Whiteboard online tool.
