| Popis: |
The paper analyzed causes of startup inrush current of three-phase PWM rectifier, researched influence of initial phase angle of grid electromotive force and initial phase angle of AC side voltage on startup current, and proposed a method to use output of phase-locked loop to control initial phase angle of the grid electromotive force, which can avoid big startup current of a phase when starting, so as to make difference of three-phase AC currents between each other be not vary much. The experimental results verify correctness of the theoretical analysis and validity of the method. |
