Compact Submodule With Protruding Bus Bars For Power Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power compensation devices require multiple submodules, making them bulky and difficult to install in defined spaces due to the need for extensive space for insulation and cooling systems.
Innovation Solution
A submodule design featuring a compact structure with protruding input bus bars and a bypass switch outside the power pack, along with a frame and insulation units, allows for efficient stacking and reduced volume, enabling easier installation and improved space utilization in power compensation devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional power compensation device includes a plurality of submodules, then the power compensation function is achieved, but the device occupies excessive space and cannot be installed in a defined space
Solution Approach 1:
The patent merges multiple submodules into a single integrated power pack unit. The power pack contains multiple switching modules that function together as a unified submodule, eliminating the need for separate submodule housings and reducing overall device volume while maintaining the power compensation function.
Solution Approach 2:
The power pack is designed as a multi-functional unit that performs the functions of multiple submodules simultaneously. By integrating multiple switching modules within a single power pack, the device achieves universal functionality that replaces several traditional submodules, thereby reducing space requirements.
2Reliability
If multiple submodules are provided in a power compensation device, then the power compensation capability is enhanced, but the installation complexity and difficulty increase
Solution Approach 1:
The patent combines multiple switching modules into a single power pack unit, reducing the number of discrete components that need to be installed. This integration simplifies the installation process by reducing the number of connection points and assembly steps required while maintaining enhanced power compensation capability.
Solution Approach 2:
The patent segments the power compensation device into modular power packs that can be independently installed and configured. Each power pack contains integrated switching modules that function as a complete submodule unit, making installation easier while maintaining the capability for enhanced power compensation through multiple packs.
3Reliability
If conventional submodules are used, then the power system compensation is achieved, but the space for insulation and cooling systems becomes excessive
Solution Approach 1:
The patent merges the insulation and cooling systems into a compact integrated design within the power pack. By combining multiple switching modules into a single unit, the insulation and cooling infrastructure can be shared and optimized, reducing the total space required for these support systems while maintaining reliable power system compensation.
