Abstract:

In accordance with an example embodiment, there is disclosed herein a technique for the formation of power sharing groups by a power supply module. The power supply module sends a discovery message and eventually receives the discovery message back. The power supply message also receives a discovery message from at least one other power supply module. The power supply module determines whether it is a master of the group, and if the power supply module is the master of the group, the power supply module determines power budgets for the at least one other power supply module. After obtaining a power supply budget, a controllable switching device is closed enabling power to be shared with the at least one other power supply module.
