This paper introduces a discrete model of the two_phase current control. The static compensation performance and the frequency spectrum under the conditions of rectifier load or asymmetry source are studied by this model. The results show that its compensation performance is satisfactory and the total harmonic distortion is low. Researches on the dynamic compensation performances are also carried out by simulation under the condition of the sudden variation of the inverter input DC voltage and load current. The researches show that the two_phase current control has the advantage of fast dynamic respones and low transient impulsion. It is able to run after the current command rapidly.
