Claim Text:
1. A power conversion system, comprising: a first power conversion module coupled with a power source module via one or more first input terminals, wherein the first power conversion module is configured to convert a first input power at the one or more first input terminals to a first output power at one or more first output terminals for providing to a load module, the first power conversion module comprising a first source side converter, a first load side converter, and a first DC link coupled between the first source side converter and the first load side converter; a second power conversion module coupled with the power source module via one or more second input terminals, wherein the second power conversion module is configured to convert a second input power at the one or more second input terminals to a second output power at one or more second output terminals for providing to the load module, the second power conversion module comprising a second source side converter, a second load side converter, and a second DC link coupled between the second source side converter and the second load side converter; and a controller in electrical communication with the first power conversion module and the second power conversion module, wherein the controller is configured to generate a number of switching signals according to a circuit structure of the power source module or a circuit structure of the load module, wherein the switching signals are provided to the first power conversion module and the second power conversion module to balance a first DC link voltage at the first DC link and a second DC link voltage at the second DC link.
