Abstract: A power converter that gives priority to the high power output and only provides power to the low power output when the total potential output power is equal to or less than the rated power of the power converter. A specific power threshold is established, and when the high power output remains below this threshold for a period of time the low power output is allowed to turn on.

Subsequently, the high power output is checked against the threshold to determine if the low power output can be turned on again. If the high power output is below the threshold, then the low power output is turned on.
