The need for more power

The need for more power

Almost everything around us is touched at some point by robots. There are robotic applications utilized in agricultural harvesting, warehouse inventory movement, campus delivery and consumer delivery. These robots are fueled by batteries, making power conversion efficiency – along with size/weight – critical. Power conversion needs become more and more challenging as load capacity, visual recognition and user functionality requirements further increase within the robotic application.

Longer range and run time with more payload and functionality

A better way to deliver power: Power delivery networks based on Vicor high-performance power modules enable innovative designs for robots. More flexible than a brick and easier to implement than a discrete solution, each power module is optimized for high-efficiency, density and overall performance. Vicor modules are also lightweight compared to competitive solutions, enabling robots to take on larger and heavier payloads. Power modules can also be paralleled, allowing for designs to easily scale in power as robotic power demands increase and also allow for the same power architecture to be deployed within a platform of various sized robot systems.

Power delivery network for robots using a 67V battery 

The first powertrain architecture highlights the PRM power module, a high-performance buck-boost regulator. The PRM creates an intermediate bus of 24V to 48V with 96 to 98% efficiency to power servos and additional downstream power modules, including fixed ratio NBMs, ZVS Buck and ZVS Buck-Boost regulators. All modules can also be paralleled for higher power conversion.

Power delivery network for robots using a 24 to 48V battery 

The second powertrain architecture highlights the use of direct conversion from the battery to the point-of-load. PRM, ZVS Buck, and ZVS Buck-Boost regulators support these applications. One example is the PI3740 ZVS Buck-Boost regulator which provides more than 100W of power from a 10 x 14 x 2.5mm SiP package with peak efficiencies of up to 96%.
