Which group DCM 48V Bus Converter belongs to and how it is built
Power Systems is a subcategory of hardware components responsible for managing electrical power in a robot or its modules. It encompasses power supplies, power distribution modules, voltage converters, protection circuits, battery management systems (BMS), and other power infrastructure elements. In robotics, power systems are critical to the reliability, safety, and stable operation of all subsystems.
A Power Supply Unit is a component responsible for delivering and regulating electrical power to electronics, drives, and actuator modules. In robotics, power supplies may power individual components or entire systems, providing appropriate voltage and current parameters along with protection against electrical interference. A PSU can operate as an AC/DC or DC/DC converter, or as part of a more complex power distribution system.
The DCM (DC-DC Converter Module) 48V Bus Converter is an isolated DC-DC converter by Vicor, designed for 48 V bus architecture (Factorized Power Architecture – FPA). DCM modules function as isolated bus-to-bus converters, delivering regulated or unregulated output voltage with high conversion efficiency of up to 97%.
The DCM series is available in a compact ChiP (Converter housed in Package) form factor with power density exceeding 1000 W/in³. Wide input voltage ranges (typically 36–75 V for the 48 V variant) allow integration with mobile and humanoid robot power systems using a 48 V bus. Galvanic isolation protects control electronics from the power section.
In robotic architectures, the DCM 48V Bus Converter typically serves as the first conversion stage – transforming the high-voltage bus from the battery pack to a 48 V level, from which servo motors, point-of-load converters, and computing systems are powered. Modules are available in various power ratings (typically 50–400 W).
