Abstract
A power converter circuit is coupled to an AC power input, a backup power input, a first capacitive element and a second capacitive element. The power converter circuit is configured to, in a line mode of operation and during a positive portion of an AC input voltage, convert the AC input voltage into a positive DC output voltage through a first inductive element and provide a charging voltage to a backup power source through a second inductive element using a negative DC output voltage stored in the second capacitive element, and, in the line mode of operation and during a negative portion of the AC input, convert the AC input voltage into the negative DC output voltage through the second inductive element and provide the charging voltage to the backup power source through the first inductive element using the positive DC output voltage stored in the first capacitive element.
