摘要
分析了准Z-源DC-DC变换器在稳态时的工作原理,根据状态空间平均法建立了准Z-源DC-DC网络在电流连续工作模式下(CCM)的交流小信号模型,并对模型进行分析,获得控制至输出的传递函数,实现了输出电压闭环控制。最后建立了实验样机,进行了实验验证。
Operation principle of quasi-Z-source DC-DC converter in the steady state is analyzed in this paper.State space av- eraging method is used to establish AC small signal model of a quasi-Z-source DC-DC converter network in continuous conduction mode.The model is analyzed,and the control-to-output transfer function is attained,closed-loop control of the output voltage is achieved.Finally,experimental prototype is established,and experimental verification is performed.
