Medical imaging systems for healthcare systems, medical facilities, data centers
Static UPS systems have long switching times and poor performance, and no output voltage regulation, while online configurations suffer from lower efficiency due to double stage power conversion.
The patented system is a cost effective and compact DC line-interactive UPS system for replacing with the AC online UPS employed in the medical imaging machine like CT scan machine. The proposed DC UPS is integrated with a safe and high-power density battery, which links to the DC bus of the medical machine. In case of utility power disruptions, the system provides power from the battery to directly energize the DC section and ensure continue and reliable operation.
The system will also provide load leveling for the main AC/DC rectifier which has not been offered by conventional AC UPS systems. It applies load power smoothing to reduce the rating of the incoming AC line and consequently reduces the installation cost and time. Moreover, the new UPS technology improves CT scanner up-time, reliability, efficiency, and cost, and is applicable to other imaging modalities such as MR and X-ray as well.
