| 摘 要： | 介绍了单级光伏系统的拓朴结构和工作原理,着重阐述了用电导增量法实现最大功率跟踪(MPPT)的基本原理。根据光伏阵列的特性,设计了一套能实现最大功率跟踪的新型光伏并网逆变器。该逆变器采用单级结构,控制部分采用基于DSP(TMS320LF2407)控制的最大功率跟踪和电流跟踪控制策略,实现了与网压同步的正弦电流输出及高功率因数运行。

| Abstract: | The grid-connected photovoltaic system is a trend of photovoltaic system development.This paper introduces the topology and operation principle of single-stage photovoltaic system,illuminates mainly the principle of realizing Maximum Power Point Tracking(MPPT) with conductance increment method.According to the character of solar array,we designed a novel grid-connected photovoltaic inverter with the function of MPPT.The inverter consists of a single-stage construction.We adopt the MPPT and current tracking algorithm via a DSP controller.As a result,the sinusoidal wave output current is synchronized with grid voltage,and operation is at high power factor. |
