Abstract

A non-isolated quadratic boost high gain dc to dc converter is proposed in this paper. The converter has a wide gain ratio than conventional high gain boost converters. Along with the high voltage gain the proposed topology has a single switch and reduced voltage stress across switch and diodes. Moreover, the converter draws continuous input current which makes the proposed converter an attractive choice for renewable energy applications. Simulation is carried out in PLECS software. The software is specially designed to determine the efficiency of the converter by considering switching and conduction losses. A 50W laboratory prototype of the proposed converter is developed. The theoretical, simulated and experimental results closely agree with each other.

具有低电压应力的单开关高增益DC-DC变换器
本文提出了一种非隔离二次升压高增益dc - dc变换器。该变换器比传统的高增益升压变换器具有更宽的增益比。除了高电压增益外,所提出的拓扑结构具有单个开关和降低开关和二极管之间的电压应力。此外,该变换器的连续输入电流使该变换器成为可再生能源应用的一个有吸引力的选择。在PLECS软件中进行仿真。该软件是专门设计的,通过考虑开关和导通损耗来确定变换器的效率。开发了50W变换器的实验室样机。理论、仿真和实验结果吻合较好。
