摘要

本文提出了一种用于住宅并网光伏系统的单相两级逆变器。该系统由开关型DC-DC升压变换器和h桥逆变器组成。该逆变器的开关策略是根据电网同步条件，采用正弦波脉宽调制和方波调制相结合的开关策略。利用MATLAB对该逆变器在并网场景下的性能进行了仿真。此外，采用简单的最大功率点跟踪(MPPT)方法实现智能光伏组件系统，并利用功率平衡来提高系统效率。

Single Phase Grid-Connected Inverter forPhotovoltaic System with Maximum PowerPoint Tracking

This paper proposes a single-phase two stage inverter for grid-connected photovoltaic systems for residential applications. This system consists of a switch mode DC-DC boost converter and a H-bridge inverter. The switching strategy of proposed inverter consists with a combination of sinusoidal pulse width modulation (SPWM) and square wave along with grid synchronization condition. The performance of the proposed inverter is simulated under grid-connected scenario using MATLAB. Furthermore, the intelligent PV module system is implemented using a simple maximum power point tracking (MPPT) method utilizing power balance is also employed in order to increase the systems efficiency.
