| Abstract: | For the existing problems of centralized photovoltaic power system structure, DC module photovoltaic power system structure is introduced and the flyback converter is taken as the front end DC module of the DC module photovoltaic power system. A variable step hysteresis comparison method is adopted to realize the maximum power point tracking control, and a voltage close loop control strategy with voltage feed forward control is used to stabilize the DC bus voltage. The experimental results demonstrate the feasilibity of the solution scheme. |
