摘要对双向Buck/Boost变换器带恒功率负载时的稳定性问题进行了研究。首先对电机控制器的直流侧双向Buck/Boost变换器提出了一种功率前馈控制策略。分析了恒功率负载负阻抗特性不利于母线电压稳定的机理, 对双向Buck/Boost变换器提出了一种反映直流母线电压变化趋势的前馈控制策略抵消了负阻抗特性对直流母线电压的影响。小信号模型分析、仿真和实验结果都证实了这种控制策略能够有效抵消恒功率负载负阻抗特性对母线电压稳定性的影响, 有利于提高驱动系统稳定范围。

Abstract：In this paper, the stability of bi-directional Buck/Boost converter with constant power load (CPL) is studied. A novel power feed forward control scheme for the bi-directional Buck/Boost is presented. The mechanism of negative impedance of CPL degenerating bus voltage stability is analyzed and a control scheme can counteract negative impedance with feed-forward term which reflectes the changing trends of DC bus voltage is proposed. Small-signal model analysis and simulation and experimental results demonstrate that the proposed control scheme can counteract the impedance negative of CPL effectively and improve the drive system stability range.

Key words： Buck/Boost bi-directional converter motor drive system constant power load negative impedance characteristics DC-bus voltage stability
