Abstract

DC-DC converters exhibiting minimal input and output ripple are extensively employed across a diverse range of applications. This paper presents a proposed modification to the DC-DC Cuk converter. The converter is developed by modifying a conventional Cuk DC-DC converter to exhibit boost characteristics. The DC-DC converters possess the capability to function as versatile units that can be employed in a multitude of applications, ranging from DC-DC conversion to DC-AC conversion (inversion). This paper presents a novel DC-DC converter design that aims to achieve reduced ripple in both input and output currents. By employing the principle of mutual inductance, it is possible to further mitigate the presence of ripple current. The analysis of the impact of mutual inductance on the output voltage and ripple current of the proposed converter has been conducted. The validity of the derived analytical method has been confirmed through both simulated and experimental investigations. The utilization of mutual inductance in the proposed modified Cuk converter has been demonstrated to result in reduced current ripple.

互感对降低改进型 DC-DC Cuk 转换器输出电流纹波的影响分析

直流-直流转换器具有最小的输入和输出纹波，被广泛应用于各种不同的应用领域。本文提出了一种直流-直流 Cuk 转换器的改进方案。该转换器是通过修改传统的 Cuk DC-DC 转换器来实现升压特性的。直流-直流转换器具有多功能单元的功能，可用于多种应用，从直流-直流转换到直流-交流转换（反转）。本文介绍了一种新型直流-直流转换器设计，旨在减少输入和输出电流的纹波。通过采用互感原理，可以进一步减轻纹波电流的存在。我们分析了互感对拟议转换器输出电压和纹波电流的影响。通过模拟和实验研究，证实了推导出的分析方法的有效性。事实证明，在拟议的改进型 Cuk 转换器中利用互感可降低电流纹波。
