【摘要】 提出了一种新型带Z源的Cuk电路(简称为Z-Cuk电路),在开关导通比不超过0.5时,该电路即可实现Cuk电路的升降压效果,使得仅通过一级变换便可得到更高的升压倍数,且开关导通比并不大。分析了其工作原理,仿真和实验结果证实了该电路的有效性。更多还原

【Abstract】 A novel Cuk converter with Z-source is proposed,which is named Z-Cuk converter.Only with duty ratio less than 50% can the topology realize the function of Cuk converter,thus gaining higher Boost coefficient through only one conversion.Its operation principle is analyzed and the simulative and experimental results verified its validity.更多还原
