Research on MPPT Algorithm in Medium & Small Size PV System

In order to improve the maximum output power of a photovoltaic(PV) cell,an improved CVT algorithm is put forwarded for the reality of application in medium and small size photovoltaic system in connection with the property of photovoltaic cell.The method is emulated by MATLAB simulation.Analysis and simulation results show that the method can improve the precision of MPPT effectively compared with the normal CVT algorithm.
