Abstract： |
The invention belongs to the light volt generating system controlling technology domain, the independent light volt generating system based on the maximal power point tracing technology includes: (1)the solar cell (2)the storage cell (3)BUCK circuit (4)the light voltage combining net system. Because of the light volt cell array having the dP/Dv and I almost linear characteristic connection when working in the maximal power working point and the stable working zone. The invention is aiming at the adopt the light volt array output circuit, the MPPT controlling of the light volt array can be realized by controlling BUCK circuit accounting empty percent as the power switching tache or the PWM driving signal of the combining net system reverse changing machine. When the light intension has the quick change, the light volt array output circuit can trace the change with the lineal, the quick and the smooth mode, the light volt cell array maximal power point trace controlling can be realized better. |
