Fig. 16(a) and (b) shows the circuit configuration of two parallel connected inverters, along with the operation waveforms. Output ac currents on both the inverters have sinusoidal waveforms with unity power factor. Each amplitude of output ac current can be determined individually, depending on the current command of the individual inverter. In this case, the output currents, Iac1 and Iac2 , of these inverters are 0.6 A and 0.3 A, respectively, and the total output current, Iac = 0.9 A, is injected into the utility line. We can see that the proposed inverters can attain stable, parallel operation.
