摘要
本文介绍了合肥工业大学能源研究所设计的一种采用直流无刷电机的光伏水泵的控制器。该系统以Motorola公司的电机控制专用芯片68HC908MR16单片机为核心,采用一种实用的MPPT(最大功率点跟踪)控制方式,实现了太阳电池的TMPPT(真正的最大功率跟踪)功能。给出了实验波形,符合理论设计的预期要求。
A control method for photovoltaic pump based on sensorless brushless DC motor was presented. The system was controlled by 68HCg08MR16 which was developed by MOTOROLA as special chip used in for motor control. A simple practical control method of solar array maximum power point tracking was adopted, so that the maximum power point tracking control of the system was realized,
