Patent ID: 8810217

Claim:
A power converter system, comprising: a first voltage converting module for converting an input voltage to a first output voltage; a second voltage converting module for converting the input voltage to a second output voltage, the second voltage converting module being connected in parallel with the first voltage converting module; at least one signaling line between the first voltage converting module and the second voltage converting module; and a current share controller operatively connected to communicate with the first and second voltage converting modules using a Power Management Bus protocol to establish a master-slave relationship between the first and second voltage converting modules such that one of the first and second voltage converting modules comprises a master voltage converting module and the other of the first and second voltage converting modules comprises a slave voltage converting module; wherein the first and second voltage converting modules are configured to operate in a current share configuration so as to share a load current of the power converter system, wherein the master voltage converting module is configured to determine its output current and send a current share signal indicative of its output current to the slave voltage converting module via the at least one signaling line, and the slave voltage converting module is configured to adjust its output current in dependence upon the current share signal from the master voltage converting module; wherein the master voltage converting module is configured to send a pulse width modulated signal to the slave voltage converting module via the at least one signaling line, a pulse width of the pulse width modulated signal being indicative of the output current of the master voltage converting module; and wherein the slave voltage converting module is configured to measure the pulse width of the pulse width modulated signal and adjust its output current in dependence upon the measured pulse width.
