Solution Overview
Problem
Existing power distribution systems face inefficiencies in managing power requests from multiple electrical loads, leading to potential overloads and increased distribution losses, as they lack a centralized control mechanism to optimize power allocation and prioritize loads effectively.
Innovation Solution
A power distribution system with a master device that receives power requests from sockets, determines the optimal power to be provided to each socket based on overall system capability and priority information, and controls DC power converters to ensure efficient power distribution, including the option for bypassing conversion for non-converted power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a centralized master device controls power allocation for all sockets, then power distribution efficiency is improved and losses are reduced, but device complexity increases
Solution Approach 1:
The master device serves as an intermediary that receives power requests from multiple sockets, determines optimal power allocation based on overall system capability, and sends controlling signals back to sockets. This centralized coordination reduces power distribution losses by optimizing allocation while managing system complexity through a dedicated control unit.
Solution Approach 2:
The system implements feedback mechanisms where sockets transmit power requests to the master device, which then sends controlling signals back to regulate power delivery. This closed-loop control enables dynamic optimization of power distribution, reducing losses while maintaining manageable complexity through structured communication protocols.
2Loss of energy
If the power supply operates at high voltage (e.g., 400V), then power distribution losses are reduced, but safety risks and insulation requirements increase
Solution Approach 1:
The system replaces traditional low-voltage AC distribution with high-voltage DC distribution, substituting the mechanical/electrical conversion infrastructure with a direct DC architecture. This reduces conversion losses and simplifies the system while managing safety through electronic control and standardized high-voltage DC components.
3Adaptability or versatility
If DC power converters are used at each socket to convert high voltage to load-specific voltages, then adaptability to different loads is improved, but device complexity and energy losses increase
Solution Approach 1:
The system applies local quality by enabling DC power conversion at individual sockets only when and where needed, rather than universally. The master device intelligently determines which sockets require conversion and which can directly supply power to loads, optimizing the balance between adaptability and energy efficiency.

AI summary
The invention relates to a power distribution system for distributing power from a power supply (2) to several electrical loads (4, 5) via sockets (3). The sockets receive power requests from the electrical loads and transmit the power requests to a master device (9) which controls the power to be provided by the respective socket based on the received power requests. Since the master device receives all power requests from the sockets and has therefore an overview of the overall power requirements, the master device can determine the power to be provided by the respective socket under consideration of this knowledge. This can lead to an improved determination of the power to be provided by the respective socket and hence to an improved overall power distribution.
