A novel high step-up converter

A high step-up converter is presented herein, which is constructed mainly by stacking bootstrap capacitors combined with inductor-coupled boost converter with active voltage clamp. Above all, this converter can be implemented based on low turns ratio with the relatively small number of components used. Furthermore, under different input voltages and different output currents, the variations in voltage stress for each component are slight. In this paper, some experimental results are provided to verify the feasibility and effectiveness of the proposed topology.
