| The mathematic model of three-phase current-source PWM rectifier is studied in this paper, and its main control methods are analyzed and compared. Researches on the space vector modulation technology of the three-phase current-mode PWM rectifier are mainly studied. After the analysis of variety SVPWM synthesis, several modulation methods with relatively good performances to meet the actual needs are found by simulation and analysis of the spectrum of different methods of synthesis vector comparison between the pros. The three-phase current-mode PWM rectifier under the conditions of power imbalances has been studied, and a compensation method of three-phase current curb-side PWM rectifier current net negative sequence components in the state of voltage unbalanced.
