摘要

本文介绍了一种基于电容存储的光伏系统DC-DC变换器的MPPT算法的实现。在所提出的光伏系统中，采用脉冲宽度调制(PWM)技术控制ZETA变换器，采用增量电导(incc - cond) MPPT算法，实现了从发电机向负载的最大功率传输，其中选择合适的占空比步长和计算响应时间非常重要。在MATLAB/Simulink中对所提出的光伏系统进行了仿真，仿真结果表明，基于电容存储的DC-DC变换器与基于增量电导算法的光伏系统相比具有优势。

Implementation of incremental-conductance MPPT algorithm in a photovoltaic conversion system based on DC-DC ZETA converter

This paper presents the implementation of an MPPT algorithm into a capacitor storage based DC-DC converter destined to photovoltaic systems. In the proposed photovoltaic system, ZETA converter controlled by the pulse width modulation (PWM) technique is studied with the Incremental Conductance (Inc-Cond) MPPT algorithm which allows transferring the maximum of power from the generator to the load where choosing a suitable duty cycle step size and computing the time of response are very important. This proposed photovoltaic system is simulated in MATLAB/Simulink, The obtained results show the advantage of using capacitor storage based DC-DC converters with the photovoltaic system in which the maximum power point is always achieved thanks to the Incremental-Conductance algorithm.
