Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face challenges in scaling power distribution due to rapid growth in CPU power consumption and high rates of change in electronic data processing devices, leading to issues like branch circuit tripping and power failures, especially with single power supply equipment vulnerable to downtime and complex maintenance requirements.
Innovation Solution
The development of a high-density, modular, and scalable automatic transfer switch (ATS) system that allows for efficient power distribution with minimal rack space usage, incorporating locking power cord technologies and polyphase power switching, enabling secure and efficient power delivery in data centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power distribution systems are used with single power supply equipment, then equipment simplicity is maintained, but reliability deteriorates due to vulnerability to downtime and power failures
Solution Approach 1:
The power distribution system is segmented into multiple independent power sources (primary and secondary) with automatic transfer switches at different levels (panelboard ATS and equipment-level micro-ATS). This segmentation allows the system to maintain simplicity at the equipment level while achieving high reliability through distributed redundancy across multiple segments of the power distribution architecture.
2Reliability
If multiple automatic transfer switches are deployed throughout the data center, then reliability is improved through redundancy, but device complexity increases due to additional switching components
Solution Approach 1:
The system divides power protection into two segmented layers: facility-level ATS at the panelboard and equipment-level micro-ATS integrated with individual devices. This segmentation distributes the redundancy function across multiple components, achieving high reliability without requiring a single complex centralized switching system.
Solution Approach 2:
The micro-ATS is integrated directly into the equipment, allowing each device to autonomously manage its own power source switching. This self-service capability eliminates the need for complex centralized control of multiple external ATS devices, reducing overall system complexity while maintaining redundancy.
3Power
If power distribution infrastructure is expanded to accommodate growing CPU power consumption, then power capacity is improved, but floor space efficiency deteriorates due to increased rack space requirements
Solution Approach 1:
The micro-ATS integrates power switching functionality into the vertical dimension of equipment racks rather than requiring additional horizontal floor space. By embedding the ATS within the equipment itself or integrating it into the rack structure, the system expands power capacity vertically without consuming additional data center floor area.
4Reliability
If traditional power cord connections are used without locking mechanisms, then ease of operation is improved for plugging and unplugging, but reliability deteriorates due to loose connections and power failures
Solution Approach 1:
The system replaces simple mechanical plug-and-play connections with a more sophisticated mechanism involving locking power cords and automatic transfer switches. The locking mechanism provides secure electrical connection while the micro-ATS automatically detects and responds to connection issues, maintaining reliability without significantly impacting ease of operation.

AI summary
Systems and methods are provided for reliable redundant power distribution. Some embodiments include micro Automatic Transfer Switches (micro-ATSs), including various components and techniques for facilitating reliable auto-switching functionality in a small footprint (e.g., less than ten cubic inches, with at least one dimension being less than a standard NEMA rack height). Other embodiments include systems and techniques for integrating a number of micro-ATSs into a parallel auto-switching module for redundant power delivery to a number of devices. Implementations of the parallel auto-switching module are configured to be mounted in, on top of, or on the side of standard equipment racks. Still other embodiments provide power distribution topologies that exploit functionality of the micro-ATSs and/or the parallel micro-ATS modules.
