摘要
提出了一种带Z源的Sepic直流变换电路,分析了其工作过程,对调压机理进行了理论推导,并与传统Sepic电路做了对比。该电路在开关导通比<0.5时就能实现升降压功能,仿真和实验结果证实了电路的有效性.
A Sepic DC/DC Inverter with Z-source is proposed in this paper.Its working process is analyzed,its mechanism of voltage adjusting is deduced.This circuit is compared with traditional sepic circuit,the circuit can fulfill the function of boost-buck when conduction ratio less than 0.5 and the simulative and experimental results verified its validity.
