This paper presents a new topology of single-stage inverter to generate quality sinusoidal output waveform without any additional boosting components. The proposed inverter is a combination of back-to-back two Cuk converters and hence, it is named as a cuk inverter. As per the inductor value, it can operate in continuous and discontinuous current mode. The sinusoidal output voltage can be raised or lowered with different duty ratio based on the load requirement. This Cuk inverter reduces the filter requirement in the output circuit. Further, to show the advantage of the proposed topology, a comparative study is carried out with conventional and recent converters in terms of number of switches, LC components and applications. The performance of the proposed topology is analyzed with MATLAB/Simulink tool and implemented as hardware to validate the simulated results.

用于隔离负载应用的新型无变压器 Cuk 逆变器拓扑设计

本文提出了一种新的单级逆变器拓扑结构，无需任何额外的升压元件即可生成高质量的正弦输出波形。所提出的逆变器是背靠背两个 Cuk 转换器的组合，因此，它被命名为 cuk 逆变器。根据电感值，它可以工作在连续和不连续电流模式。正弦输出电压可以根据负载要求以不同的占空比升高或降低。该 Cuk 逆变器降低了输出电路中的滤波器要求。此外，为了展示所提出拓扑的优势，我们在开关数量、LC 组件和应用方面与传统和最近的转换器进行了比较研究。
