UPS FOR MEDICAL IMAGING SYSTEM

摘要

Apparatus for energizing a large scale medical imaging system, preferably in the form of a CT scanner, so that the scanner operates off an uninterruptable power supply (40) in the event that the external power (46) falls below sufficient power to operate the system so that system operation remains uninterruptable. The system is designed to operate off a broad range and types of external power supplies (46) including those providing DC, single or three phase AC power. The system therefore can operate from a common single phase AC outlet. In addition, power factor correction (80) is provided so that the system can correct for phase differences between the voltage and current at the input line (46) created by the input impedance of the system.
