摘要

本文分析了用于光伏(PV)应用的三级级联交错升压变换器的设计,以将PV输出电压提升到高电压比。三级交错升压变换器的串联级联产生更高的电压。交错升压变换器采用最大功率点跟踪控制,利用增量电导技术调节系统的占空比以获取PV的最大功率。利用MATLAB/Simulink对光伏电池系统和电源变换器进行了建模设计和分析。结果表明,该系统具有较低纹波电流的高电压功率转换能力。

A High Voltage Ratio Three-stage Cascaded Interleaved Boost Converters for PV Application
This paper analyses the design of three-stage cascaded interleaved boost converters for a Photovoltiac (PV) application to step-up the PV output voltage to a high voltage ratio. Higher voltage is produced due to series cascading of three-stage interleaved boost converters. The Interleaved Boost Converter is controlled by Maximum Power Point Tracking using Incremental Conductance technique to regulate the duty cycle of the system to harvest the maximum power of the PV. The modeling of PV cell system and power converter is designed and analyzed by MATLAB/Simulink. The results prove that the proposed system design has high voltage power conversion with less ripple current.
