Abstract
An inverter system is provided, by which the magnitudes of currents flowing through inverter modules are substantially equal. The inverter system includes multiple inverter modules connected in parallel, where input terminals of all the multiple inverter modules are connected to a same direct current input bus, and output terminals of all the multiple inverter modules are connected to a same alternating current output bus. An input contact Sof the direct current input bus and an output contact Sof the alternating current output bus are such located that a difference between impedances of any two branches between Sand Sdoes not exceed a preset value.
