Robot power systems: how to choose the right DC-DC converter

In modern robotics, power management is one of the key factors to ensure the performance of robots. robotics DC-DC converter, as an important part of the power system, can efficiently regulate the voltage to provide robots with the power they need.

CHONDA TECHNOLOGY will discuss the role of robotics DC-DC converters in robot power systems, especially in applications such as industrial robots and medical robots, and provide guidance on selecting the right DC-DC converter.

The Role of robotics DC-DC Converters in Robotic Power Systems

A DC-DC power module is a power management device that converts an input voltage to a desired output voltage. Power converters enable innovation in robotic applications. Its main role in a robot power system is to provide a stable power supply to various components.

For example, in industrial robots, DC-DC converters provide a stable voltage to motors, sensors, and control systems to ensure efficient robot operation. In medical robots, the stability and efficiency of DC-DC power supply are particularly important, as they must operate under precise and reliable conditions to ensure patient safety.

The Importance of Choosing High-Efficiency DC-DC Converters

Most semiconductor components can only operate at DC. Therefore, electrical products that operate in sockets require an “AC/DC converter” that converts AC (alternating current) 100V to DC (direct current).

The ICs on the circuit boards of the entire machine have their own inherent operating voltage ranges and require different voltage accuracy. If power is supplied from a power source with unstable voltage, it may cause malfunctions, degradation of characteristics, or other abnormalities.

Therefore, it is necessary to use a “DC/DC converter” to convert and stabilize the required voltage. The following are some of the key factors:

Input Voltage: Ensure that the DC-DC converter you select is capable of accepting the robot’s power supply input voltage range. Different robot applications may use different voltage sources, and choosing the right input voltage will prevent system overload or instability.

Output Voltage: The output voltage must match the voltage requirements of each component of the robot. For example, sensors may require a 5V supply, while motors may require a 12V or 24V supply. Therefore, when selecting a robotics DC-DC converter, make sure its output voltage range meets the needs of all components.

Conversion Efficiency: A high-efficiency DC-DC converter minimizes energy loss and improves the overall efficiency of the robot. Choosing a high-efficiency power module not only extends the robot’s runtime, but also reduces heat generation and energy waste.

Power requirements for common robots

The power requirements for specific types of robots are determined by the application:

Agricultural Harvesting Robots: Planting, tending, and harvesting crops (fruits, vegetables, grains) can be accomplished through automated vehicle guidance technology coupled with vision recognition and a variety of environmental and soil analysis sensors. These large robotic vehicles are typically powered by high voltage DC power supplies of 400 V or more.

Delivery robots: Deliver a variety of different products to consumers or parks in the last mile. Although the size and weight of the load varies, these robots are typically powered by 48 V to 100 V batteries and have higher runtime requirements than warehouse and stockpile moving robots.

Warehouse Inventory Moving Robots: Perform inventory management and order fulfillment tasks in large warehouse environments. These robots are typically powered by 24 V to 72 V battery power and are randomly recharged as needed.
