Abstract
A power conversion system includes n (n being an integer of 2 or more) power conversion devices (Pto P) connected in parallel to a load (); and a communication line () connected to the n power conversion devices (Pto P). Each of power conversion devices includes a communication circuit () which transmits a load current value detected by a current sensor () to each of other (n−1) power conversion devices through the communication line (), and receives (n−1) load current values transmitted through the communication line () from other (n−1) power conversion devices; and an operation circuit () calculating a shared current and a cross current of the corresponding power conversion device based on the n load current values. Accordingly, a wiring line is prevented from becoming complicated even when the number of power conversion devices is increased.
