摘要

本设计论文对车顶太阳能电池阵电动汽车(RSC-EV)现有的电网提出了一些改进。提出了一种集成开关电感网络(SZSIC)的开关z源dc-dc变换器，用于在直流链路中从低电压到高电压的转换。通过在传统z源dc-dc变换器的输出端增加一个开关和二极管，用前端的开关-电感网络代替电感，将电压增益提高到(1+D)/(1−7D)。通过与现有dc-dc升压网络升压能力的比较，本方案实现了更高的电压增益。本文对所提出的SZSIC的性能进行了分析，并通过仿真结果进行了验证。本文探讨了采用开关电感和开关z源设计高压增益直流电源升压变换器的思路。

An ultra-high-voltage gain DC-DC converter for roof-mounted solar cells electric vehicle

This deign paper proposed few improvements on the existing electrical network in the roof-mounted solar array based electric vehicle (RSC-EV). A switched Z-source dc-dc converter integrated with switched-inductor networks (SZSIC) is proposed for the conversion from a low voltage to a higher one in the dc link. The voltage gain is increased to (1+D)/(1−7D) by replacing inductor with switched-inductor network of the frontend and adding another one switch and diode to the output terminal of the traditional Z-source dc-dc converter. Comparing the boost capabilities of existing dc-dc step-up network, higher voltage gain is realized in the proposed SZSIC. The performances of the proposed SZSIC are analyzed in this paper, and then validated by simulation results. This paper explores the idea of employing switched-inductor and switched-Z-source to design boost converter for high voltage gain DC power supplies.
