摘要

本文对电动汽车、插电式混合动力汽车和光伏并网应用中广泛使用的硬开关高升压dc-dc变换器拓扑结构进行了性能分析。从文献中可以明显看出，在部分遮阳条件下，光伏并联配置在效率方面优于串联配置。另一方面，电动汽车充电站或并网光伏汽车对前端直流电压水平要求较高;因此，本文回顾了流行的高升压dc-dc变换器拓扑结构，包括开关计数、启动电流和固定电压增益的无源元件。

Performance analysis of non-isolated high step-up dc-dc converter topologies used in photovoltaic grid connected electric vehicle charging stations

This paper presents performance analysis of widely used hard switched high step-up dc-dc converter topologies in electric vehicle(EV) or plug-in hybrid electric vehicles or in photovoltaic grid connected applications. It is evident from the literature that PV parallel connected configuration is better in terms of efficiency over series connected configuration under partial shaded condition. On the other hand, the electric vehicle charging stations or grid connected PV vehicle demands higher front end dc voltage level; therefore, this paper reviews popular high step-up dc-dc converter topologies in terms of switch count, startup currents and passive components for a fixed voltage gain.
