Customer’s challenge

Last-mile consumer delivery of groceries, take-out food and online consumer items is the mission-critical task of these autonomous robots. While payloads vary in size and weight, these robots typically have long run times and are typically powered by 48V to 100V batteries. Delivery robots are equipped with a variety of sensors, cameras, and GPS technology to navigate their surroundings safely and efficiently. These robots depend on batteries, which pose a challenge for their operational range. The key goals were:

Extend range and run time
Compact and lightweight solution to save space
Supporting a variety of point-of-load voltages

The Vicor solution

Vicor high-performance power modules reduce space and weight on board, increasing space for sensors and navigation systems and enabling delivery robots to carry larger loads and objects. The high efficiency levels of Vicor power modules increase operating time allowing them to reach more distant destinations safely.

Key benefits

Modular design supports flexible design requirements

Compact high-density power modules optimize available design space

High efficiency solution extends available battery life

Power delivery network

The DCM™ converter series fits the needs for this class with operation from 43 – 154V input. The DCM3623 enables a regulated 24 or 48V distribution from the battery for servo drives, other payloads and downstream converters. The DCM3623 provides 240W of power at 90% efficiency from a 36.38 x 22.8 x 7.26mm package. With a 24 – 48V rail established, ZVS buck or buck-boost regulators can typically be used to power lower voltage rails.
