Abstract
This article proposes a novel single-input-multi-output (SIMO) converter for photovoltaic (PV) applications. The proposed structure produces multi-outputs with extended n stages. The voltage gain of the proposed topology for each output is enhanced by adding the number of the stage which in turn increases the power. The voltage across the switch is low, so it leads to using a lower RDS (ON) MOSFET. Besides, the peak voltage of the switch and diodes is reduced by enhancing the number of the stage. Thus, the proposed converter's power loss is reduced. This structure can operate in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) of operations. The proposed structure is capable to achieve maximum power point (MPP) using perturb and observe P&O) technique. To describe the foremost advantages of the proposed converter, comparison results between the recommended topology and other related structures in this field are presented. The dynamic analysis, and the principle of operation for n = 3, 4 stages are introduced. Finally, experimental results in CCM and DCM operations with 50 kHz switching frequency are provided.
