| Abstract: | This context studied single stage photovoltaic inverter , improved and got the single stage power decoupled photovoltaic inverter . The inverter can achieve maximum power point tracking control and output voltage control in single stage. The mathematical model of the system is established by using the state space averaging method. A novel single-stage power decoupling inverter is proposed, which can effectively increase the range of DC side input voltage. According to the topological characteristics, paper proposed an improved SPWM control method. The coordination problem between MPPT and output voltage is solved. Finally, the rationality and feasibility of the topology are verified by simulation and experiment. |
