论文摘要
CUK和SEPIC是用于充电电池的重要DC-DC转换器。在本文中，用于CUK和SEPIC转换器的广义平均技术。派生方程用于获得开路传输函数的频率响应。使用LTSpice软件包模拟了扰动输出电压与占空比（$ G_ {VD} $）的比率。转换器的平均模型有助于更快，更简单的模拟。还模拟了CCM和DCM中转换器的行为。派生的表达式可以通过两个开关推广到电源转换器。
Cuk and SEPIC are some of the important DC-DC converters used for charging batteries. In this paper, a generalized circuit averaging technique is employed for Cuk and SEPIC converters. The derived equations are used to obtain the frequency response of open loop transfer function. The ratio of perturbed output voltage to duty cycle ($G_{vd}$) is simulated using LTSpice software package. The derived averaged models of the converters aids in faster and simpler simulation. The behavior of the converters in CCM and DCM was also simulated. The derived expressions can be generalized to power converters with two switches.
