چکیده

This paper proposes an ultrahigh step-up DC-DC converter consisting of two boosting stages, a coupled inductor, and switched capacitors. The salient features of the proposed converter comprise its high voltage gain, the low voltage stress on its power switches, the continuity of its input current, and the existence of a common ground between the source and load. As well as it requires an inductor and a coupled inductor with smaller sizes in comparison to the compared references which causes its operation with higher efficiency. The input ripple of the suggested step-up converter is low and the lower input ripple leads to the utilization of the presented step-up converter in renewable energy applications. Also, the torque of the DC motor is controlled by the PI controller. The presented ultrahigh step-up converter is simulated in MATLAB and the operation validity of the proposed converter is proven with MATLAB simulation
