| Abstract: | Single-stage grid-connected photovoltaic(PV) systems have many advantages,including large capacity,high efficiency and low cost.A fast current control method is required for PV power generation systems to maximize the high-quality output power.Based on the concepts of single-phase single-stage grid-connected photovoltaic system,a comparison is conducted to characterize the equivalence of deadbeat control and one cycle control which can be applied into inverters.Simulation programs for the control schemes ar... |
