Abstract: Current sensing is one of the important functions in a dcdc converter. It may be used for overcurrent protection, current control, or load sharing among paralleled converters. Current sharing (CS) can be achieved by sensing the output currents of individual converters, but it requires $N$ current sensors. In this paper, a current-sensing and CS scheme that uses a single sensor to sense the individual currents is presented. The scheme is independent of the number of converters in the paralleled system. The proposed scheme can be implemented easily on a digital platform and provides various functionalities of a voltage-regulating module. The analysis and implementation issues for such a scheme are presented and experimentally verified on a 1-V/25-A two-phase interleaved buck converter with digital control. © 2006 IEEE.
