摘　　要：研究了一种应用于微型光伏逆变器的最大功率点跟踪(MPPT)策略,详细分析了变步长扰动观察法的工作原理和控制策略,通过Matlab/Simulink仿真平台验证了该方法可以快速、稳定地实现最大功率点跟踪,并通过变步长扰动观察法在微型光伏逆变器中的应用实验,验证了这种方法可以极大地提高微型光伏逆变器的转换效率。The tracking strategy of maximum power point（MPPT） was studied, which was apptied 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 photovoitaic inverter, the efficiency of micro photovoltaic inverter, which could be greatly improved, was verified.
