Efficiency of cuk converter waveforms generator#

Therefore a suitable DC-DC converter and MPPT controller is required to obtain maximum power. The linear and unstable nature of PV array inhibits maximum production of power. Of all these energies solar energy is the cheap and abundant power available. Renewable energy sources like wind, solar energy, and tidal energy will be a solution for this. Long term utilization of fossil fuels has depleted their availability and there is a quest towards new energy resources.

Keywords: PV Generator Improved P&O MPPT Soft switched Cuk Converter Hybrid SMC The prototype model developed with SMP085P module validates the performance of modified Cuk converter. Peak power is harvested from PV panel and optimal operating point is detected using HSM based MPPT method.

Performance analysis of the Passive soft switched Cukconverter and conventional converter is illustrated by simulation and experimental methods for various irradiation changes. 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. 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. Sliding Mode Controller (SMC) is implemented in an Analog -Digital way. 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. 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.
