Generator and Rectifier Feedback Control for AC/DC Fault Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power generation control systems experience inherent control delays due to separate control functions for AC and DC power stages, which can lead to delayed fault correction in aerospace and other applications.
Innovation Solution
A system with integrated generator and rectifier controllers for direct communication and feedback, allowing for immediate fault detection and modulation of power outputs across both stages to mitigate control delays and ensure quick fault response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control functions are used for AC and DC power stages, then each stage can be controlled independently, but control delay occurs when fault events need correction
Solution Approach 1:
The patent combines the AC stage controller and DC stage controller into a unified control system where both controllers are operatively connected for direct communication. This merging allows fault detection and correction to propagate immediately between stages, eliminating the time delay associated with separate independent control functions while preserving the ability to control each stage independently through the direct communication channel.
2Speed
If direct communication is implemented between controllers, then fault detection and correction speed improves, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the AC stage controller and DC stage controller exchange operational status and fault information through direct communication. Each controller monitors its own stage and provides feedback to the other, enabling rapid fault detection and correction. This feedback-based approach achieves fast response speeds without requiring complex centralized control, as each controller independently processes feedback from its stage and communicates only essential information to the other controller.
