Patent ID: 8148958

Claim:
A power control device, comprising: a synchronization node configured to carry a synchronization signal, wherein the synchronization signal is employed by the power control device to initiate a time frame comprising a plurality of time slots and to control a switching activity of a power switch of a DC to DC converter; and a current sharing bus node, wherein the power control device transmits a digital signal in a designated time slot in the plurality of time slots on the current sharing bus node, wherein the power control device determines a value of a load current of a power converter employing current data received on the current sharing bus node from a further power control device, and wherein the power converter comprises the power control device and the further power control device, and the plurality of time slots comprises a frame, wherein the frame comprises an indicator of a start of the frame, and wherein the power control device employs the indicator of the start of the frame to synchronize a determination of the value of the load current of the power control device with a related determination of a value of a load current of the further power control device.
