Abstract
A power converter system disclosed herein includes first and second voltage converting modules, for converting input current to output voltage, and a current share controller configured to establish a master-slave relationship between the first and second voltage converting modules. As a result, one of the first and second voltage converting modules acts as a master module, and the other acts as a slave module. The first and second voltage converting modules are arranged to operate in a current share configuration so as to share a load of the power converter system. The master module determines its output current and sends a signal indicative of its output current to the slave module via at least one signaling line connecting the master and modules to the current share controller. The slave module adjusts its output current in dependence on the signal from the master module.
