Remote Reprogramming Power Semiconductor Logic via Central Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating programmable logic in power semiconductor components require significant manual effort, especially in systems with multiple components, as technicians must physically connect programming tools to each unit, leading to high operational costs and inefficiencies.
Innovation Solution
A method and electrical circuit where control signals are used to send programming signals to a processor in the output stage, allowing for remote reprogramming of programmable logic, eliminating the need for direct manual intervention and enabling centralized control for multiple units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual programming is performed at each power semiconductor device location, then programming can be done individually, but the effort and time required increases significantly with the number of devices
Solution Approach 1:
A central controller is introduced as an intermediary between the programming tool and multiple power semiconductor devices. The central controller receives programming signals and automatically distributes them to connected power stages, eliminating the need for technicians to manually connect to each device individually and significantly reducing programming time
Solution Approach 2:
The programming signals are copied from a single source and distributed to multiple power semiconductor devices through the central controller. This allows the same program update to be applied to numerous devices simultaneously through signal replication rather than individual programming operations
2Ease of manufacture
If a service technician manually connects programming tools to each power semiconductor device, then direct programming is possible, but operational costs and complexity increase
Solution Approach 1:
Multiple individual programming operations are merged into a single centralized programming process. The central controller combines the function of programming multiple power semiconductor devices into one unified system that can be operated from a single location, simplifying the overall programming process despite adding a central control component
3Productivity
If programming is performed while the power semiconductor device is operational, then continuous operation is maintained, but malfunctions may occur during programming
Solution Approach 1:
The system switches the logic to programming mode before actual programming begins, which disables control signal output in advance. This preliminary action prevents any potential malfunctions during the programming process while maintaining the ability to resume normal operation afterward, ensuring both safety and continuous productivity
