Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing direct voltage conversion devices suffer from significant heat losses and require bulky heat dissipation due to the transfer of all power through electronic components and transformers, leading to inefficient power handling and increased component size.
Innovation Solution
The conversion device employs superposition and rectification means connected to both the first conversion means and transformation means, reducing the power transmitted through the transformer and allowing for smaller electronic components, with identical winding directions on the primary and secondary windings to minimize power constraints on components and the transformer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If all power is transferred through electronic components and transformer, then power conversion is achieved, but heat losses increase and component size increases
Solution Approach 1:
The patent segments the power transfer path into two separate paths: one through the transformer for voltage transformation and another through the superposition means for direct power transfer. This segmentation allows only the necessary portion of power to pass through the transformer, reducing heat losses while maintaining full power handling capability.
Solution Approach 2:
The superposition means act as an intermediary component that directly transfers power from the first conversion means to the output without requiring full power to pass through the transformer. This intermediary path reduces the power burden on the transformer and associated electronic components.
2Power
If all power is transferred through electronic components and transformer, then power conversion is achieved, but component size increases
Solution Approach 1:
By segmenting the power transfer into separate paths through the transformer and superposition means, each component handles only the necessary portion of power, allowing for smaller component sizes while maintaining overall power handling capability.
Solution Approach 2:
The superposition means serve as an intermediary that reduces the power burden on the transformer and electronic components, enabling smaller component sizes for the same overall power handling capability.
3Power
If identical winding directions are used on primary and secondary windings, then power constraints on components are minimized, but transformer design becomes more specific
Solution Approach 1:
The patent specifies a particular parameter configuration for the transformer windings (identical winding directions) that optimizes the power transfer characteristics and minimizes power constraints on components. This parameter change is integrated with the superposition topology to achieve reduced component stress.
