摘要

本文介绍了一种以DC-DC升压变换器为第一级，以单相全h桥逆变器为第二级的两级独立光伏系统的有效设计和控制。由Perturb和Observe MPPT控制的DC-DC变换器，在不同天气条件下实现最大功率。此外，全h桥逆变器拓扑以及两个控制回路被用作系统和负载之间的链接。为了减轻电压和电流中可能出现的噪声，设计了一种二阶无源电感电容器(LC)滤波器。利用Matlab/Simulink软件对系统进行了实现，并对相关结果进行了讨论。

Design and Control of Two-Stage Standalone Photovoltaic Generation System

This paper introduces an effective design and control of a two-stage standalone photovoltaic system consisting of a DC-DC boost converter as the first stage and a single-phase full H-bridge inverter as the second stage. The DC-DC converter controlled by Perturb and Observe MPPT to achieve maximum electric power under different weather conditions. Moreover, the full H-bridge inverter topology along with two control loops are used as a link between the system and the load. To mitigate noises that could occur in both voltage and current, a second order passive Inductor Capacitor(LC) filter is conceived. Implementation of the system is done by Matlab/Simulink Software and relevant results are discussed.
