Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular multilevel power converters for high-voltage and medium-voltage applications are often large and require extensive planning and infrastructure, leading to lengthy deployment times due to the need for fixed installations and complex approval procedures.
Innovation Solution
A modular multilevel power converter design where electrical components are arranged on multiple vehicles, such as truck trailers, allowing for quick transportation and deployment without the need for permanent infrastructure, with components remaining on vehicles and connected via conductors for easy setup and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If modular multilevel power converters are designed for high-voltage and medium-voltage applications, then the output voltage capability is improved, but the size and weight of the converter increase
Solution Approach 1:
The power converter is divided into multiple independent modules (first electrical components on first vehicle, second electrical components on second vehicle) that can be separately transported and assembled. Each module handles a portion of the total power conversion task, enabling high-voltage capability through modular scaling without requiring a single large heavy converter.
2Stability of the object's composition
If fixed construction and infrastructure are implemented, then the structural stability is improved, but the deployment time and complexity increase
Solution Approach 1:
The system transitions from a static fixed installation to a dynamic mobile configuration. Vehicles provide the structural base and can be moved to different locations as needed. The electrical components remain stable during operation while the entire system can be rapidly repositioned, combining operational stability with deployment flexibility.
Solution Approach 2:
The vehicles serve multiple functions: they provide structural support for electrical components, enable transportation to deployment sites, and can be repositioned for different applications. This multi-functionality eliminates the need for separate infrastructure elements, reducing deployment time while maintaining operational stability.
3Adaptability or versatility
If components are distributed on multiple vehicles, then the transportability is improved, but the system complexity increases
Solution Approach 1:
Multiple vehicles carrying different electrical components are merged into a single integrated power conversion system through electrical connections. The first vehicle carries components such as rectifiers or inverters, while the second vehicle carries complementary components, and their combination achieves the complete power conversion function with enhanced transportability.
4Reliability
If conventional fixed installation procedures are followed, then the installation reliability is improved, but the approval and planning procedures become more protracted
Solution Approach 1:
Electrical components are pre-assembled and tested on vehicles at manufacturing locations before deployment. This preliminary assembly and validation ensures installation reliability is achieved in advance, eliminating the need for complex on-site installation procedures and lengthy approval processes for permanent infrastructure changes.
