Abstract:

The photovoltaic (PV) generation is one of the most important renewable sources of energy and presents significant worldwide growth every year.The classical cuk DC-DC converter is a step-up/step-down topology with input and output current source characteristics. The step-up static gain of the classical cuk converter may not be enough for a low voltage PV module and the operation at steady-state with an extreme value of duty-cycle cause high current and voltage stress with low efficiency operation. In order to solve these drawbacks a voltage-lift switched inductor technique is applied to the classical cukconverter. The structure presents a voltage-lift topology and two input inductors and two switches comparing with the classical topology that presents only one switch and one input inductor. But the input current is shared in these components and the switch voltage is reduced. These characteristics are interesting for applications with high input current that is the case of low input voltage source. The simulation is done using MATLAB/Simulink R2017a software. The control circuitwas implemented using dsPIC30F2010 controller and results are verified.Experimental results obtained from a 180W converter prototype confirm the theoretical considerations and the simulation results.
