Abstract
A control circuit is provided for controlling two power converters in a master-slave current sharing relationship. The control circuit is adapted to detect a presence of a dynamic load condition, control the two power converters in a default master-slave current sharing mode based on a current sharing correction function, and in response to detecting the presence of the dynamic load condition, disable the current sharing correction function so that the two power converters are controlled in a modified master-slave current sharing mode to substantially prevent oscillation between output currents of the two power converters. The control circuit may be one or more components of the power supply including the two power converters. Other example power supplies, control circuits and control methods are also disclosed.
