Switchable Power Busbar Layout for Series-Parallel Output Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Direct current power supplies are limited to a single output mode (high-voltage or high-current) due to fixed series or parallel connections of internal power modules, failing to meet diverse user requirements.
Innovation Solution
A power busbar device with interleaved trace and insulation layers, incorporating switching contact groups and switches, allows power modules to be connected in series or parallel, enabling simultaneous high-voltage and high-current output selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power modules are connected in fixed series or parallel configuration, then the device structure is simple and reliable, but the device can only provide one output mode (high-voltage or high-current) and cannot meet diverse user requirements
Solution Approach 1:
The patent applies the dynamics principle by making the connection configuration changeable through switching contact groups and switches. The power modules can dynamically switch between series and parallel connections based on user needs, transforming a static fixed-configuration system into a dynamic multi-configuration system that adapts to different output requirements.
Solution Approach 2:
The patent implements universality by designing a single power supply device that can perform multiple functions - providing both high-voltage output (series connection) and high-current output (parallel connection). The switching contact groups enable the same hardware to serve different purposes, making one device replace what would traditionally require multiple dedicated devices.
2Adaptability or versatility
If switching contact groups and switches are added to enable series or parallel connection, then the device can provide multiple output modes, but the device structure becomes more complex
Solution Approach 1:
The patent applies nesting by integrating the switching contact groups and switches directly within the busbar structure. The switching components are embedded in the connection path between power modules, nesting the control functionality within the existing structural framework rather than adding separate external control systems.
Solution Approach 2:
The patent merges the connection function and switching control function into a unified structure. The switching contact groups are combined with the busbar connection elements, so that the same structural components serve both mechanical connection and electrical switching purposes, reducing the need for separate dedicated switching mechanisms.

AI summary
A power busbar device includes two output contacts, a plurality of insulation layers, a plurality of trace layers, a plurality of power supply contact groups, and a plurality of switching contact groups. The trace layers and the insulation layers are arranged in an interleaved stack. Each of the switching contact groups includes a first switching contact, a second switching contact, and a switch. The first switching contact, the second switching contact, and the power supply contact groups extend through the insulation layers and the trace layers. The switch enables connection or disconnection between the first switching contact and the second switching contact based on a switching state thereof. Each of the trace layers distributes traces connected to the output contacts, the switching contact groups and the power supply contact groups, to connect the power supply contact groups in series or in parallel based on the switching state of the switch.
