Harvesting robots

Various produce including strawberries, apples and lettuce are being planted, maintained and harvested using automated vehicle guidance along with visual recognition robotics. Large robotic vehicles or equipment are typically powered from a high-voltage DC source of 400V or more.

The power delivery network

In this type of design, the Vicor BCM converter series can provide high-voltage battery conversion to a safe, nominal 48V. One example is the BCM4414 capable of more than 1,600W at greater than 97% efficiency from its 111 x 36 x 9mm package. The BCM is a fixed ratio converter with an output voltage 1/16 of the input voltage. Fixed ratio or regulated point-of-load converters such as Vicor NBMs, PRMs, ZVS Buck and ZVS Buck-Boost regulators power individual, downstream, lower-voltage rails as needed.
