摘要
开发了一种新型的独立光伏充放电控制系统,在最大功率跟踪(MPPT)方面以恒定的电压初值启动,开机后迅速跟踪到光伏电池的最大功率点.同时,把MPPT跟踪和充电方法结合起来,提出了一种新的三阶段充电策略.最后通过实验验证了恒压启动的MPPT和充电策略的有效性、正确性.
A new independent system of solar charging controller was designed, maxi-mum power point tracking with a constant initial voltage, can improve the speed of MPPT during entire system＇s startup process. At the same time, by combining MPPT with charging methods, a new three phase charging strategy was proposed. The experimental results verify the correctness and effectiveness of the proposed method.
