Integrated Capacitor Component with Shared Busbar Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capacitor components, such as DC-link capacitors and Y capacitors, have a poor volume filling factor due to separate housings and power supplies, leading to inefficient use of space in radially symmetrical installation spaces.
Innovation Solution
Integration of a first capacitor and a Y capacitor into a single component, where the Y capacitor is formed by connecting two capacitors in series and parallel with the first capacitor, sharing a common voltage supply and housing, and using busbars for electrical contacting to minimize the number of connection points and optimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DC-link capacitors and Y capacitors are designed as separate components with own housings and power supply, then each capacitor can be optimized independently, but the volume filling factor is poor and space utilization is inefficient
Solution Approach 1:
The patent combines DC-link capacitors and Y capacitors into a single integrated capacitor component with a common housing and shared power supply connections. This merging eliminates the need for separate housings and reduces the overall volume required, directly improving the volume filling factor while maintaining the functional independence of each capacitor through internal configuration
2Ease of operation
If each capacitor is provided with its own connection point to the power supply, then electrical connection is simplified, but the device complexity increases and space is wasted
Solution Approach 1:
The patent implements a universal power supply connection system where a single set of power supply terminals serves both the DC-link capacitors and Y capacitors. The busbar structure enables multiple capacitors to share common connection points, reducing the number of required connection points while maintaining ease of electrical connection through the integrated design
