【 摘 要 】

References(13)Cited-By(1)An input filter is indispensable for a matrix rectifier (MR), since it can improve the input current quality and reduce the ac supply voltage distortion. However the characteristics of input filter reduce the input power factor (IPF). Moreover, the unbalanced ac supply voltage could disturb dc output voltage. Consequently, this paper provides a novel approach to achieve both tight dc output voltage and unity IPF at the main ac power supply by applying circuit DQ transformation to MR. Analyzing the DQ model of MR, sliding mode control (SMC) based on reaching law is used to achieve tight dc output voltage regulation of MR and PI control is applied to control the q-axis current to be zero. Finally, simulation and experiment results are shown to verify the effectiveness of the control scheme proposed in this paper.
