一种太阳能电池MPPT控制器实现及测试方法的研究

Implementation of MPPT Controller in Photovoltaic Array and Research of Testing Method

本文根据太阳能电池的特性 ,设计了一种基于"电压扰动法"的太阳能电池最大功率点跟踪 (MPPT)控制器 ,并提出了一种简单、实用的模拟太阳能电池对控制器进行测试的方法 ,理论证明该方法是可行的 ,并得到实际验证。在此实验方法下 ,对设计的MPPT控制器进行测试 。

According to the characteristics of photovoltaic(PV) array, a controller with PV array maximum power point tracing (MPPT) is designed, which is based on 'voltage harassing' method. And a testing method for this controller is proposed, which is simple and practical, and can simulate some specialities of PV array. It is proved that the proposed method is right theoretically and is available practically. The designed controller is tested using the method. The result indicates it has better performance for MPPT.
