UPS Control Module Layout for Reduced Cabinet Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing uninterruptible power supply devices with thyristors in bypass current paths increase in width due to adjacent placement of power conversion and control modules, leading to increased left-right dimensions.
Innovation Solution
Arranging thyristor and control units in a front-rear direction intersecting the left-right direction within the control module housing, overlapping them for reduced width, and using common components across multiple power conversion modules to minimize overall device width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the thyristor unit and control unit are arranged in the left-right direction in the housing, then the ease of operation and maintenance is improved, but the width of the control module increases
Solution Approach 1:
The patent applies dimensionality change by arranging the thyristor unit and control unit in the front-rear direction (depth dimension) instead of the left-right direction (width dimension). This allows both units to be accessed from the front side for maintenance while reducing the width of the control module, thus resolving the contradiction between ease of maintenance and module width.
2Ease of manufacture
If the module accommodating the power conversion unit and the module accommodating the thyristor unit and control device are disposed adjacent to each other in the left-right direction, then the ease of manufacture is improved, but the width of the entire uninterruptible power supply device increases
Solution Approach 1:
The patent reduces the width of the entire device by arranging components in the front-rear direction within the control module housing, rather than expanding the left-right width. This maintains ease of manufacture through standardized modular design while minimizing the overall device width.
3Length of stationary object
If the thyristor unit and control unit are arranged in the front-rear direction in the housing, then the width of the control module is reduced, but the ease of operation and maintenance may be worsened
Solution Approach 1:
The patent resolves this contradiction by arranging both the thyristor unit and control unit in the front-rear direction such that both can be accessed from the front side of the housing. This configuration reduces the width of the control module while maintaining ease of maintenance, as neither unit needs to be accessed from the rear or side.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the left-right width of the control module and the entire uninterruptible power supply device, enhancing installation and maintenance accessibility while minimizing component count and device complexity.
Implementation Method 1
a thyristor unit that includes a thyristor provided in a bypass current path for outputting AC power to the load external to the device without passing through the power conversion unit
Implementation Method 2
a power conversion unit that converts power fed from an AC power supply or a battery external to the device and feeds the converted power to a load external to the device
