摘要

采用最大功率点跟踪(MPPT)技术的光伏(PV)泵浦系统旨在在各种日照和温度条件下为泵浦获得尽可能高的功率，从而克服光伏板与泵浦负载之间的不匹配。本文提出了一种跟踪最大功率点并迫使系统在这些点附近运行的简单方法。采用MC68HC908GP32单片机实现MPPT控制器。实验结果表明，采用MPPT技术的光伏泵浦系统具有良好的性能。

Implementation of a stand-alone photovoltaic pumping system with maximum power point tracking

Photovoltaic (PV) pumping systems using a maximum power point tracking (MPPT) technique aim to obtain the highest possible power to the pump under various insolation and temperature conditions, thus overcoming the mismatch between the photovoltaic panel and the pumping load. A simple method of tracking the maximum power points and forcing the system to operate close to these points is presented in this paper. The MC68HC908GP32 microcontrol unit (MCU) is employed to implement the proposed MPPT controller. Experimental results show the performances of a photovoltaic pumping system with the MPPT technique.
