摘要: This paper proposes a two degree-of-freedom (2 DOF) control of Push-Pull converter to meet the loop robustness goals as well shape output voltage response according requirement standalone photovoltaic system. The design process controller is found effective for 48V 445V dc-dc with push-pull topology. It basically Photovoltaic module fed available battery level in input. controlled at 445 V and expected produce constant AC from it using VSI (voltage source inverter). Simulation results along controller, confirm system be able regulated DC even presence considerable perturbation load current, change input internal parameters like inductance capacitance.
