摘要

本文对采用交错DC-DC转换器的太阳能光伏系统进行了性能分析对比研究。从太阳能光伏等效电路出发，建立了太阳能光伏的数学模型。在大多数应用中，太阳能光伏系统的输出需要提升到所需的电压水平。这可以通过将合适的升压转换器连接到太阳能光伏系统来实现。分析了不同类型的交错DC-DC变换器对太阳能光伏发电性能的影响。根据输出电压增益、所需开关数量、占空比、输出波形波纹和变换器效率进行分析。介绍了改进型二次升压变换器(IQBC)在太阳能光伏发电中的性能，并与传统升压变换器(CBC)和传统交错升压变换器(CIBC)进行了比较。MATLAB/Simulink仿真结果表明，采用IQBC的太阳能光伏系统性能优于传统的变流器。

A Comparative Study of Performance Analysis of Solar PV With Interleaved DC-DC Converters

This paper presents the comparative study of the performance analyses of the Solar (PV) system interfaced with interleaved DC-DC converters. The mathematical model of solar PV is developed from it equivalent circuit. The output of solar PV system needs to be boosted to the required voltage level for most of the applications. This can be achieved by connecting a suitable boost converter to the solar PV system. The performance of solar PV with different types of interleaved DC-DC converters are analyzed. The analysis is carried out in terms of output voltage gain, number of switches required, duty cycle, and ripples in the output waveform and efficiency of the converter. The performance of solar PV with Improved Quadratic Boost Converter (IQBC) is presented and compared with Conventional Boost Converters (CBC) and Conventional Interleaved Boost Converter (CIBC). The MATLAB/Simulink results proves that the performance of solar PV with IQBC is superior compared to conventional converters.
