摘要

本文提出了一种新的DC-DC变换器拓扑结构，该拓扑结构对从可再生低压直流电源获得高电压仰角系数的能力做出了关键贡献。所提出的升压原理是基于两个隔离直流电源的单源发电，串联连接以馈电负载。每个直流源都是由经典升压DC/DC转换器的重新设计提供的。这种特性对于可再生能源之间的接口是必需的，因为可再生能源有时没有足够高的电压输出来连接到电力电子设备。这种无变压器拓扑的另一个优点是减少了功率开关设备的数量。

High step-up DC-DC converter for renewable energy harvesting applications

This paper proposes a novel DC-DC converter topology that has as key contribution the capability of achieving high voltage elevation factor from renewable low voltage DC source. The proposed step-up principle is based on the generation from a single source of two isolated DC sources, connected in series to feed the load. Each DC source is provided by a redesign in the classical boost DC/DC converter. This feature is needed for interface between renewable sources that at times don't have a voltage output high enough to be connected to the power electronics. The other advantage that comes along with the proposed transformer-less topology is the reduced number of power switching devices.
