Power conversion system with N power converters

A power conversion system, connected with at least one load, each of the at least one load having two input terminals, and the power conversion system comprising:

• N power converters, wherein each of the N power converters comprises a terminal with a first type and M terminals with a second type, the M terminals comprise a first terminal and a second terminal, and each of the N power converters receives a DC power through the corresponding terminal with the first type, wherein the first terminal of a first power converter of the N power converters and the second terminal of an N-th power converter of the N power converters are connected in parallel to form an N-th total terminal to transfer an N-th total power, and the first terminal of an i-th power converter of the N power converters and the second terminal of an (i−1)-th power converter of the N power converters are connected in parallel to form an (i−1)-th total terminal to transfer an (i−1)-th total output power, wherein i is an integer greater than or equal to 2 and less than N, and N is an integer, and M is an integer smaller than N;
• wherein a terminal with one of the first type and the second type is an input terminal, and a terminal with another of the first type and the second type is an output terminal;
• and
• wherein the two input terminals of each of the at least one load are connected with two corresponding total terminals of N total terminals, respectively, wherein a (2k−1)-th power converter of the N power converters is connected with a first power source, and a 2k-th power converter of the N power converters is connected with a second power source, wherein k is greater than or equal to 1, k is less than or equal to (N/2), and k is an integer;
• wherein a power of the first terminal and a power of the second terminal are regulated, respectively.
