Power Supply Module Merging AC and DC Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power supply systems in data centers require a large number of power modules due to the redundancy needed for reliable alternating current power distribution, leading to increased costs and equipment size.
Innovation Solution
The system employs two voltages, a second alternating current and a third high voltage direct current, which back up each other, allowing fewer power modules to be used by eliminating the need for expensive UPS equipment and using a battery group for power backup only in the high voltage direct current branch, thereby reducing costs and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two sets of power supply systems are used in redundant backup mode, then power supply reliability is improved, but the number of power modules increases and cost increases
Solution Approach 1:
The patent combines multiple power supply inputs (first AC, second AC, and DC power supply) into a single power module that can accept any of these inputs. The power module includes a selecting unit that chooses the appropriate input power source, merging the functionality of multiple separate power supply systems into one integrated unit, thereby reducing the total number of power modules needed while maintaining redundancy.
Solution Approach 2:
The power module is designed with multi-functionality to accept different types of power inputs (AC and DC) and automatically adapt to the available power source. The selecting unit enables the power module to function with any combination of power supplies, making it a universal power conversion unit that eliminates the need for dedicated power modules for each input type.
