Zusammenfassung:The invention provides an input series type combination inverter system. The system includes equalization modules and sub modules, wherein the equalization modules are multiple, the sub modules are one more than the equalization modules, input ends of the sub modules are connected with the equalization modules, and the equalization modules and the input ends of the sub-modules connected with the equalization modules are equalized; when output sides of the sub modules are connected in parallel, power equalization of the output sides of the sub modules is achieved by the output current equalization control strategy; when the output sides of the sub modules are connected in series, power equalization of the output sides of the sub modules is achieved by the output voltage equalization controlstrategy; when the output sides of the sub modules are independent, respective power output of the sub modules is respectively performed according to the respective load demand. The system is advantaged in that the system is
