【Abstract】 By adjusting the circuit, MPPT can always derive maximum power output from photovoltaic cells under any external condition. The behavior mathematical model of photovoltaic cell was built, aiming at the shortcomings of the traditional MPPT in tracking speed and tracking precision. An improved MPPT method based on integral controller was researched in detail. A MATLAB/Simulink model was set up. The simulation result indicates that it has better performance when compared with traditional MPPT method.更多还原
