摘　　要：为解决传统BOOST结构太阳能收集电路在某些状况下的电流失控问题,在收集回路中引入可动态切换的光源电阻,利用光源电阻的阻值限制电流增大,利用光源电阻的光照提高光伏电池的发电能力,并通过MPPT控制实现光伏电池输出功率最大化。理论分析和仿真实验结果表明,改进后的BOOST结构太阳能收集电路在MPPT控制下,光伏电池可全程工作在其MPPT工作点附近,并全程保持最大功率输出。In order to overcome the current runaway phenomenon of the traditional BOOST structure solar energy collection circuit under some conditions,a dynamically switchable light source resistor is introduced into the collection circuit,the resistance value of the light source resistor is used to limit the current runaway,the illumination of the light source resistor is used to improve the power generation capacity of the photovoltaic cell,and the output power of the photovoltaic cell is maximized through MPPT control.The theoretical analysis and simulation results show that the improved BOOST structure solar energy collection circuit can work near its MPPT working point in the whole process under the MPPT control,and has the maximum power output in the whole process.
