The tracking strategy of maximum power point(MPPT) was studied, which was applied to micro photovoltaic inverter, and the working principle and control strategy about variable step perturbation and observation method were detailed analyzed. Fast and stable tracking of the maximum power point was verified through the platform of Matlab/Simulink. And through the applied experimental about variable step perturbation and observation method in micro photovoltaic inverter, the efficiency of micro photovoltaic inverter, which could be greatly improved, was verified.
