Abstract
In a system having multiple power supplies with outputs connected in parallel, the number of supplies providing current is controlled to improve the overall system efficiency. For example, when the output current of individual power supplies falls below a threshold, one or more supplies may be placed into a standby mode. This increases the output current of the supplies that are in an operational mode, improving the efficiency of the supplies that are in an operational mode.
