KOL-Index: 10 In this paper, a high step-up DC/DC converter is proposed, which can boost low PV panel voltage or battery voltage to a high level so as to power the dc side of grid-connected PV inverter. The proposed converter is composed of an inductor, a power switch, and a coupled inductor and is derived from the integration of buck-boost and flyback for high voltage-gain achievement. Even though it ...
