Abstract
Discussed a circulating current feedback control based on virtual circulating-impedance for traditional parallel UPS which could not effective inhibit low order harmonic voltage to lead to system instability. By modeling analysis,circulating current feedback control was increased to calculate circulating impedance of parallel UPS for the purpose of low voltage harmonic suppression and reduced circulating current. Two experimental 2.5 kV·A UPS were built and paralleled. The results of experiment verify that the improved circulating current feedback control is available and efficient.关键词
