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 S1 of the direct current input bus and an output contact S2 of the alternating current output bus are such located that a difference between impedances of any two branches between S1 and S2 does not exceed a preset value.
