Modelling and control of DC–DC Ćuk converter with and voltage multiplier cells for PV applications

Abstract

This study proposes the modelling and control of a Ćuk converter with reduced redundant power processing and voltage multiplier for photovoltaic (PV) applications. The converter makes use of a perturb & observe algorithm to extract the maximum power of a single PV panel. The proposed converter is derived from the association of the and voltage multiplier cells in order to achieve the high step‐up voltage gain. This association allows a high‐voltage gain, low‐voltage and current stresses on the semiconductors. Experimental results are presented to validate the proposal a prototype with the input of 37.4 V, output voltage of 400 V and rated input power of 200 W.
