摘　　要：提出了一种新的基于改进周期平均模型的ＰＷＭ整流器控制方案。阐明了传统三角波比较控制方式和基于改进周期平均模型控制方式的内在关系。研究结果表明传统三角波比较控制是基于改进周期平均模型控制在电压放大倍数为０时的一种特例。实验结果验证了本控制方案的正确性。A new control strategy for PWM rectifier based on Modified Period Average Model(MPAM) is proposed in this paper.The internal relationship between the MPAM control and traditional subharmonic control has been released through comparative study.The analysis results show that the traditional subharmonic control is just a special case of the MPAM control when the gain factor of source voltage is adjusted to zero.Experimental results are given to verify the theoretic analysis.
