Study of Influence of Inverter Output Impedance on Circulating-current in Parallel Operation

Zeng Jian

Abstract

The article gives the expression of active and inactive power of each inverter in parallel operation. The influence of inverter output impedance on circulating current is analyzed in detail. Emulations verify the theoretic analysis. At last, a novel way to adjust the voltage which considers the influence of resistance weight in inverter output impedance is introduced. Experimental results on two three phase 60kVA UPS are given. Experiments shown the proposed voltage adjustment can decrease the circulating current in parallel operation.
