| Abstract: | Single-stage grid-connected photovoltaic(PV) systems with one cycle control(OCC) have advantages,including large capacity,high efficiency,and low cost.Based on the analysis of OCC strategy,the mathematics model of single-phase single-stage grid-connected photovoltaic system is established.The output current detection method is given.The control strategy is simulated with PSIM to validate its feasibility.A 6 kW grid connected inverter was designed.Simulation and experiment results prove that the method has good dynamic and static characteristics. |
| Keywords: | one-cycle control(OCC) digital control grid connected inverter current control |
