A new topological structure of photovohaic inverter is proposed. It has a simple structure, and has the ability to step up/down conversion and adapt to wide voltage range compared with the one-stage PV grid-connected inverter. Then, one-cycle control based on ARM is introduced with lower power consumption, smaller size and higher accuracy compared with the traditional one-cycle control. Finally, the control strategy is confirmed to be correct and effective by the results of simulation and experiment.
