Summary:Aiming at the problem of generating inrush current at the startup instant of three-phase voltage-type pulse width modulation (PWM) rectifiers, the principle of inrush current generation is analyzed, and a method of generating a retarded curve based on tracking differentiator (TD) is studied. The rectifier startup inrush current can be effectively suppressed by dynamically adjusting the slope of the dc bus voltage reference value. In addition, the relationship between the TD parameters and time t is investigated using the Newton iteration method. The proposed method is compared with the segmental given method, and the effectiveness and superiority of the proposed method are verified by simulation and experiment.
