Abstract
The present invention is an apparatus for providing an uninterruptible power supply for an electronic device. The apparatus includes an AC-to-DC power supply that receives an external AC voltage supply and outputs a DC voltage to the electronic device. The power supply includes a bridge rectifier that rectifies the AC voltage from the external AC voltage supply, a boost power factor correction (PFC) converter that boosts the rectified voltage, and a line isolated DC-to-DC converter that changes the boosted voltage to the operating voltage range of the electronic device. The apparatus also includes an uninterruptible power supply (UPS) subsystem that contains, a controller that monitors the external AC voltage supply for interruptions, and a high voltage isolated DC-to-DC (HVDC) converter that supplies high voltage DC power directly to the PFC converter if the controller detects an interruption in the external AC voltage supply.
