“…From the results, it can be observed that the proposed converter improved the efficiency in relation to the isolated Ćuk converter, aiming to use the converter in PV systems. The standard European (Euro) efficiency and California Energy Commission efficiency were calculated according to Vasconcelos et al [17], and their values are

This study proposes the modelling and control of a Ćuk converter with reduced redundant power processing R 2 P 2 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 R 2 P 2 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.

“…Several high-voltage gain DC-DC converter topologies have been proposed so far in the literature [8], [9], [24]- [32] Among the existing approaches the extend conversion range, cascaded converters, voltage multipliers, multilevel converters, interleaved converters, switched capacitors and coupled inductors can be highlighted [33]- [35]. The use of coupled inductors has drawn significant attention, since it allows obtaining a high static gain while using few components in the power circuit.…”

Photovoltaic (PV) systems used in DC Nanogrids present prominent advantages associated with low maintenance need and operation costs. Owing to the low output voltage of the PV module, highly efficient high-voltage gain DC-DC converters are required for connection with the DC nanogrid. This work presents a novel DC-DC converter topology with current source characteristic for PV applications and current injection in DC nanogrids. The introduced converter uses coupled inductors and switched capacitors to achieve high voltage gain with low component count and without using extreme duty ratios. Besides, the main switch is turned on with nearly zero current, thus contributing to minimized switching losses. The qualitative and quantitative analyzes of the circuit are presented in detail and a prototype rated at 200 W is developed and evaluated in the laboratory. Experimental results demonstrate efficient renewable energy conversion, where the maximum efficiency is 96.8%.
