초록
In this paper, we compose of the utility phovoltaic system with the stepdown chopper and the current source inverter to reduce pulsation of dc current and dc reactor. We study that control several ways(twice frequency of utility voltage square pulse and without the chopper) of chopper part. Therefore if voltage across the dc reactor equal to zero, it is decreased. And we control modulation factor of the chopper to operate at maximum power point around of solar cell.
