摘　　要：针对光伏建筑一体化等大功率光伏发电系统,基于双重Boost电路设计了大功率光伏MPPT控制器。电流控制采用变步长增量电阻法,通过电流寻优实现MPPT,同时确保了各电感支路实现均流。经Simulink仿真验证,该控制器的性能得到了改善,如减少了电感电流纹波,降低了损耗及对功率开关管的容量要求,证明该方法是可行的。The photovoltaic MPPT controller of high power such as BIPV system was designed based on dual Boost circuit.The variable step size incremental algorithm was applied to control current.MPPT was achieved by current optimized,which could ensure current equalization in the inductances.Simulink was carried to prove the performance improvement of that controller,such as lower inductance current ripples,loss-reducing and requirements for power transistor capacity.The method was proved feasible.
