Timing Determination for UPS Power Transfer - A simplified explanation of the abstract
This abstract first appeared for US patent application 18078573 titled 'Timing Determination for UPS Power Transfer
The patent application describes devices, systems, and methods for operating a backup power source or an uninterruptible power supply (UPS) in data centers to provide power when utility power is compromised.
- The power delivery system includes a UPS with a state timing control system that operates a bypass static switch.
- The state timing control system determines when to transition the primary system from utility power to the backup UPS based on current AC voltage conditions.
- The system performs modeling to emulate the intermediate DC voltage of an actual rectifier, particularly emulating the holdup capacitor voltage.
- The emulated capacitor voltage is obtained in real time using an input power model based on RMS utility voltage and the actual rectifier output load.
Potential Applications: - Data centers - Critical infrastructure facilities - Telecommunication centers
Problems Solved: - Ensuring continuous power supply during utility power outages - Preventing data loss and downtime in critical operations
Benefits: - Reliable backup power source - Seamless transition between utility power and UPS - Enhanced protection for sensitive equipment
Commercial Applications: Title: "Innovative Backup Power System for Data Centers" This technology can be used in data centers, telecommunication facilities, and other critical infrastructure to ensure uninterrupted power supply and prevent data loss during outages.
Prior Art: Prior art related to this technology may include patents or publications on UPS systems, power management in data centers, and backup power solutions for critical facilities.
Frequently Updated Research: Research on improving the efficiency and reliability of UPS systems in data centers may provide insights into enhancing the performance of the described power delivery system.
Questions about Backup Power Systems: 1. How does the state timing control system improve the efficiency of transitioning between utility power and UPS? 2. What are the key factors to consider when designing a backup power system for data centers?
Original Abstract Submitted
Disclosed are devices, systems, and methods for operating a backup power source or an uninterruptible power supply (UPS) that can be used in data centers and that provide a backup power source to power the data center when utility power is compromised. A power delivery system that provides power to a primary system may include a UPS with a state timing control system that operates a bypass static switch. The state timing control system can determine when to transition the primary system from the utility power supply to the backup UPS, based on the current AC voltage conditions. The state timing control system may perform modeling to emulate the intermediate DC voltage of an actual rectifier, and particularly emulate the holdup capacitor voltage. The emulated capacitor voltage can be obtained in real time by both an input power model based on RMS utility voltage and the actual rectifier output load.
