To share the loads and restrain circumfluence among parallel inverters in Stand- alone photovoltaic system (PV), it is described that a digital current sharing control technique for inverter parallel operation in detail in this paper. After the analysis of circumfluence of paralleled system on distributed-logical-control, characteristic of the power regulation, a novel digital power detection technique is deduced. With measuring and analyzing the instantaneous average current of all inverters and the output current of each inverter, both of the current components are used to control and regulate the amplitude and the phase of the output voltage. The proposed control technique on current sharing in the inverter paralleling system has been verified the good characteristic of restraining circumfluence by the results of the experiment.
