摘要

本文对电池充电系统的设计与实现进行了研究。该系统采用升压式斩波器作为动力传递。最大功率点跟踪器(MPPT)是光伏发电中从功率-电压曲线获取最大功率的一种方法。MPPT采用增量电导(IC)电流控制方法，该方法由摄动与观测(P&O)方法衍生而来。在Power Simulator软件上对模型进行了分析和仿真，并利用dsPIC30F4012进行了硬件实现。最后，对2节和3节电池进行了室内充电试验，验证了该方法的正确性。从实验结果来看，所提出的控制系统从光伏或太阳能到电能的效率，2节电池为59.21%，3节电池为58.38%(最大功率参数与P in比较)，充电2节电池为74.03%，充电3节电池为84.20% (P in和P out比较)。

Design and implementation of solar power as battery charger using incremental conductance current control method based on dsPIC30F4012

In this paper has been studied about design and implementation of battery charging system. This system applied for buck-boost chopper as power transfer. A method to receive a maximum power from power to voltage curve in photovoltaic (PV) is called maximum power point tracker (MPPT). Incremental conductance (IC) current control method is used in MPPT which is derived from perturb and observed (P&O) method. A model has been analyzed and simulated on Power Simulator software also with the hardware implementation using dsPIC30F4012 have done. Finally, laboratory test to charge 2 and 3 batteries have been done to verify this method. From the experimental result, efficiency of the proposed control system from PV or sun energy to electrical energy are 59.21% for 2 batteries and 58.38% for 3 batteries (comparison between maximum power in parameter with P in), and the converter efficiency are 74.03% for charging 2 batteries and 84.20% for charging 3 batteries (come from comparison of P in and P out).
