POWER CONVERSION SYSTEM

A power conversion system includes N power converters. Each power converter includes an input terminal, a first output terminal and a second output terminal. Each of the N power converters receives a DC power through the corresponding input terminal. The first output terminal of a first power converter of the N power converters and the second output terminal of an N-th power converter of the N power converters are connected in parallel to form an N-th total output terminal to output an N-th total output power. The first output terminal of an i-th power converter of the N power converters and the second output terminal of an (i−1)-th power converter of the N power converters are connected in parallel to form an (i−1)-th total output terminal to output an (i−1)-th total output power.
