Timing Determination for UPS Power Transfer - A simplified explanation of the abstract
This abstract first appeared for US patent application 18743943 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 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 - Emergency response centers
Problems Solved: - Ensuring continuous power supply during utility power outages - Preventing data loss and downtime in critical operations
Benefits: - Enhanced reliability and uptime for data centers - Improved disaster recovery capabilities - Cost-effective backup power solutions
Commercial Applications: Title: "Innovative Backup Power Solutions for Data Centers" This technology can be used in various industries such as telecommunications, healthcare, finance, and government sectors to ensure uninterrupted operations during power outages.
Questions about Backup Power Solutions: 1. How does the state timing control system determine when to switch from utility power to the backup UPS? The state timing control system analyzes current AC voltage conditions to make the transition decision.
2. What are the key benefits of using an uninterruptible power supply (UPS) in data centers? UPS systems provide a reliable backup power source to prevent data loss and downtime during utility power outages.
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.
