Abstract :
For the characteristics of low DC voltage output of PV array, a novel BOOST DC-AC inverter circuit is proposed, it is used DC chopper and based on the AC chopper principle. The tasks of boost and inverter are undertaken only by one level BOOST DC-AC circuits. With adjustable high voltage transfer ratio, PV inverter can be easily realized. By Matlab / SimuLink simulation and verified in the prototype, the correctness of the topology circuit and realization were proved.
