摘　　要：为充分体现交-交变频电源的优势,在传统交-交变频技术和脉冲阻塞原理的基础上,提出了一种基于脉冲阻塞原理的六相连续型交-交变频电源。该变频电源采用全控型功率器件,具有控制灵活、功率器件较少和成本较低等优点。通过对脉冲阻塞和变脉宽斩波控制策略的理论分析,推导出输出电压频率和幅值的相关表达式,实现了输出电压的变频调幅。最后,设计了以dSPACE为控制核心的六相连续型交-交变频电源的半实物仿真平台,分别在2种频率下完成相关实验。实验结果和理论分析一致,验证了基于脉冲阻塞原理的六相连续型交-交变频电源的正确性及可行性。To fully reflect the advantages of an AC/AC frequency conversion power supply,based on the traditional AC/AC frequency conversion technology and the plugged pulse principle,a six-phase continuous AC/AC frequency conversion power supply based on the plugged pulse principle is proposed.This power supply adopts a full-control power device,which has advantages of flexible control,less power devices and lower cost.Based on the theoretical analysis of plugged pulse and the variable pulse width chopping control strategy,the related expressions of output voltage frequency and amplitude are derived,thus realizing the variable frequency amplitude modulation of output voltage.Finally,a semi-physical simulation platform of a six-phase continuous AC/AC frequency conversion power supply with digital Signal Processing And Control Engineering(dSPACE)as its control core was designed,and experiments were carried out at two different frequencies,respectively.Experimental results were consistent with the theoretical analysis,which verified the correctness and feasibility of the six-phase continuous AC/AC frequency conversion power supply based on the plugged pulse principle.
