Abstract
When all kinds of power electronic equipment are connected to the power grid,their harmonic content will increase greatly.When these harmonic components follow the grid voltage input to the converter,it will affect the stability of the power electronic equipment operation.In order to ensure the normal and stable operation of the equipment,it is necessary to adopt relevant control strategies to eliminate the influence of harmonics on the current waveform.In this paper,PR controller can not only realize the non-static error tracking of AC signal,but also eliminate the specific harmonic component.When the power grid voltage contains Harmonic signals,the harmonic compensators can be connected to the original PR controller,so as to greatly reduce the influence of harmonic in the power grid voltage on the control effect.Since the output DC bus voltage of a single-phase bridless PFC will have a ripple of twice the grid frequency(100 Hz),the harmonic voltage of the twice the grid frequency will introduce 3,5,and 7 odd harmonics into the input current.In order to suppress the input current harmonics caused by the bus voltage,a notch can be added to the outer voltage loop to filter the reference current.Finally,the effectiveness of the above control strategy is verified by simulation.关键词
