Solution Overview

Problem

The existing power system communication structure, relying on a master-slave architecture, results in time delays and inefficiencies due to dependence on a central controller for responding to conditions, leading to potential power wastage and reduced reliability.

Innovation Solution

Implementing a direct communication structure between power supplies, where each power supply includes a controller to detect conditions and modify its behavior independently, such as adjusting output based on thermal, physical, or efficiency conditions, without relying on a central controller, enabling proactive responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a master-slave communication architecture with a central controller is used to coordinate power supplies, then centralized control and monitoring are achieved, but response time increases and system efficiency decreases

Engineering Contradiction:

Improveresponse timeVSAvoidcommunication architecture complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent segments the centralized control function into distributed control capabilities at each power supply unit. Each power supply controller independently monitors bus conditions and makes local decisions, eliminating the single-point bottleneck of the master controller and reducing response time while maintaining coordinated operation across the system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each power supply unit is equipped with autonomous decision-making capability to self-monitor bus conditions and self-adjust its operation without requiring commands from a central controller. This self-service approach enables immediate local responses to detected conditions, significantly reducing communication delays inherent in master-slave architectures.

Inventive Principle:

Principle #25Self-service

2Loss of energy

If power supplies depend on a central controller for responding to conditions, then centralized coordination is maintained, but power wastage increases and reliability reduces

Engineering Contradiction:

Improvepower wastageVSAvoidsystem reliability

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

Power supply controllers continuously monitor bus conditions and proactively detect potential issues before they result in failures or power wastage. By performing preliminary detection and taking preventive action, the system avoids the power loss and reliability issues that would occur if responses were delayed until a central controller processed and reacted to the same conditions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements direct feedback loops where each power supply controller continuously monitors bus conditions and immediately adjusts its operation based on real-time feedback. This closed-loop control enables rapid response to changing conditions, optimizing power utilization and preventing wastage while enhancing system reliability through continuous adaptation.

Inventive Principle:

Principle #23Feedback
