Raja Mohamed Rabi Ingeniería Hybrid SMC PV Generator Improved P&O MPPT Soft switched Cuk Converter The A soft switched Cuk converter with Improved Perturb and Observe (P&O) based Maximum power point Tracker (MPPT) that uses a Hybrid Sliding Mode (HSM) Controller is proposed to enhance performance of Photovoltaic (PV)generator . Conduction losses, voltage stress, and switching losses are reduced in soft switched Cuk converter by introducing a snubber cell which in turn improves Cuk converter efficiency .Sliding Mode Controller (SMC) is implemented in an Analog -Digital way. The main benefit of the proposed solution isthat it is possible to split theSliding Mode( SM) control equation in two terms: the first one is characterized by a combination of signals which can be defined as fast and a second part obtained by a combination of signals which can be defined as slow. The slower term suits the digital implementation because it can be treated as a linear control which works in the low frequency range and faster term implemented in analog way. Performance analysis of the Passive soft switched Cukconverter and conventional converter is illustrated by simulation and experimental methods for various irradiation changes. Peak power is harvested from PV panel and optimal operating point is detected using HSM based MPPT method. The prototype model developed with SMP085P module validates the performance of modified Cuk converter. 2019 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47471678005 https://www.redalyc.org/journal/474/47471678005/ https://www.redalyc.org/journal/474/47471678005/html/ https://www.redalyc.org/journal/474/47471678005/47471678005.epub https://www.redalyc.org/journal/474/47471678005/movil 10.22201/icat.16656423.2019.17.4.855 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.4 Vol.17 |
