Abstract :
With a common DC bus, the grid-connected inverter (GCI) modules are directly paralleled. The principle of the zero-sequence circulating current (ZSCC) is analyzed. A ZSCC control scheme is proposed which does not impact the other control objectives such as the active and reactive power transmitted from the grid-connected inverter to the gird. A simulation model of a paralleled inverter with three modules is built in MATLAB /SIMULINK7.1.
