ケーススタディ: Overhead gantry robot

Wide input voltage facilitates contactless power solution

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

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.
