| 摘 要： | Z源变换器具有新型的拓扑结构,在输入直流电源和输出变换器之间采用独特的Z源网络进行连接,以获得更好的升/降压效果.在电感电流断续条件下,对Z源直流变换器的工作状态进行了详细分析,利用稳态条件下电感平均电流为零的条件推导出Z源直流变换器的升压比,进一步分析出临界电感的计算公式,并通过仿真验证了理论分析的正确性.

| Abstract: | Z-source converter is a new topology.To obtain better boost/buck effect,a unique Z-source network is placed in between input power and output converter.This paper presents the operation states of the Z-source DC-DC converter in the discontinuous current mode.The analysis of boost factor and the critical inductor are also described.Finally,the validity of this theory is verified by simulation. |

| Keywords: | Z-source DC-DC converter discontinuous current boost factor critical inductor |
