Abstract：In the paralleled inverters, the inverter unit should have big equivalent output impedance and rigid output characteristic, since the inverter system need to restrain the circulating current and keep the output voltage constant. The analysis result indicates that the equivalent output impedance and output characteristic is affected by the parameters of the current-loop and voltage-loop in SPWM inverter with instantaneous inductor-current feedback. A simple method for designing the parameters of the inverter unit in paralleled system is proposed. Simulation and experimental results verify the correctness of the theoretic analysis.
