This article presents a novel structure for high step-up DC-DC converter. The proposed converter offers several advantages, including simple structure, voltage gain, efficiency, reduced stress on the semiconductors, and fewer components. A two-winding coupled inductor has been employed to enhance output level in this topology. suggested only one power switch with low ON-state resistance (RDS-ON...

Due to high demand for voltage boosting in the field of renewable energy sources, a novel topology step-up converter with single switch is proposed this paper. The uses coupled inductors architecture. enables control stepping-up gain by adjusting duty cycle and selecting appropriate turn ratio inductors. two circuit can act as transformer. Moreover, technique aims harness turning off stresses a...

A novel approach is proposed for a high step-up and high efficiency converter with a low switch stress. The integrated boost-flyback converter uses coupled-inductor techniques to achieve high step-up voltage with low duty ratio, and thus the slope compensation circuit is disregarded. The proposed circuit topology improving high-gain ratio, increasing efficiency, reducing the secondary side of c...

A novel high step-up DC-DC converter with coupled-inductor and switched-capacitor techniques is proposed in this paper. The capacitors are charged in parallel and are discharged in series by the coupled inductor, stacking on the output capacitor. Thus, the proposed converter can achieve high step-up voltage gain with appropriate duty ratio. Besides, the voltage spike on the main switch can be c...

This paper includes a Cockcroft-Walton (CW) high phase dc-dc voltage transition based on multiplier, with no step-up transformer. The suggested conversion approach is very appropriate for low-input dc generating systems continuous input current switch, diode or condenser low rib, and voltage. In this article two frequencies in the control techniques are used, one works order to reduce inductor ...
