75W Dual Output Isolated DC-DC Converter for Autonomous Mobile Robot (AMR) Auxiliary Power

28 Jul, 2026 12:17pm

Why Do Autonomous Mobile Robots (AMRs) Experience Navigation Errors, Camera Resets or Controller Reboots?

In AMR projects, engineers often focus on navigation software, LiDAR calibration or motion control when troubleshooting system failures. However, unstable auxiliary power is frequently the hidden cause behind navigation errors, camera resets and communication interruptions.

AMRs typically use a 48V battery system, while LiDAR, safety controllers and industrial IPCs require 24VDC, and industrial cameras, wireless modules and displays require 12VDC. Voltage fluctuations during acceleration, braking or battery discharge can affect these devices and reduce overall robot reliability.

Root Cause Analysis

Common engineering challenges include:

Battery voltage fluctuations under dynamic loads.

Multiple voltage requirements within one robot.

EMI generated by motor drives.

Limited installation space.

Continuous operation requiring high reliability.

Engineering Requirements

Engineers need a power solution that can:

Deliver stable 12VDC and 24VDC outputs simultaneously.

Simplify wiring and reduce power modules.

Provide galvanic isolation.

Resist EMI in mobile environments.

Operate reliably under vibration.

Support customized robotic platforms.
