Configurable Power Switching Controller Merging Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Programmable solid-state power switching controllers face inefficiencies due to the need for excessive components to handle maximum output ratings, resulting in unnecessary weight and control requirements for channels operating below full capacity.
Innovation Solution
A programmable power switching controller with multiple power channels and a cross-communication system, allowing channels to merge and share resources, with each channel containing a controller for coordinated operation, thereby enabling flexible current ratings without requiring each channel to support the maximum rating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If each power channel incorporates sufficient components to handle the maximum output rating, then the maximum current rating is achieved, but the weight increases due to excess components
Solution Approach 1:
Multiple power channels are merged into a single programmable power channel by connecting their load outputs together. The controllers of the individual channels coordinate to distribute the total current load across the channels, enabling the system to achieve high current ratings without requiring each individual channel to have full-power components. This reduces overall weight while maintaining maximum power capability.
2Power
If each power channel incorporates sufficient components to handle the maximum output rating, then the maximum current rating is achieved, but the device complexity increases due to associated controls
Solution Approach 1:
The controller in each power channel is designed to perform multiple functions: it controls its own channel's switching components and also participates in coordinating with other channels to distribute the total load. This multi-functionality reduces the need for separate control systems for each channel, simplifying the overall device complexity while maintaining the capability to handle maximum current ratings.
3Ease of manufacture
If channels are merged to create a merged power switching controller channel, then component usage is optimized, but the need for cross-communication between channels arises
Solution Approach 1:
A cross-communication system is implemented as an intermediary layer between the merged power channels. This system enables the controllers of individual channels to exchange information about load distribution and coordination requirements. While this adds some complexity, it provides a standardized interface that simplifies the coordination process and enables efficient component usage across the merged channels.

AI summary
A configurable power switching controller (10,100,200) includes multiple power channels (20,120,122,222), and a programming connector (160,260) that connects the load outputs of a subset of the multiple power channels thereby creating at least one merged power channel (134,238).
