“…In [11], the authors have proposed a hybrid cascaded nine level inverters for photovoltaic applications. The proposed system in [12] are based on Maximum Power Point Tracking (MPPT) combined with multilevel inverter to achieve the maximum power. In [6], the system comprises back-to-back voltage source converters with no extra dc/dc conversion stages to connect wind and photovoltaic generators to the power grid.…”

This paper covers a new topology, a synchronous wind turbine generator, and a solar photovoltaic generator. The Permanent Magnet Synchronous Generator is linked to the grid by back-to-back voltage source converters (BtB VSC), consisting of a two-stage rectifier and a five-stage Neutral Point Clamped inverter, operated by the Space Vector Pulse Width Modulation technique. A solar photovoltaic system has a direct interface with the capacitor of the DC link of the BtB VSCs, with no additional DC/DC conversion stage, while the efficiency of the system is maximized. This work features a Perturb and Observe algorithm Maximum Power Point Tracking for to extract the optimum power from both wind turbine and solar PV generator. The application of Space Vector Pulse Width Modulation control scheme is used for harmonics compensation THD. A proportional integral regulator is used to regulate the DC link voltage. A prototype is tested under various conditions, wind velocity variations as well as under several photovoltaic solar isolations. The present work has been treated using Matlab/Simulink. Simulation results proved efficiency provided by this controlling approach: reduced distortion of harmonic and increased power factor.

In this paper, a novel bidirectional multi-input energy harvesting converter (MIEC) for portable device charger is presented. Switches that are separately regulated using different duty ratios are used in the design of such an MIEC power converter. The peak power of the photovoltaic sources may be tracked using such duty ratios, and the battery power can also be managed. The switch with two directions is also a part of this converter. If necessary, the battery can be charged via a USB charger but it is also capable of supplying power to the portable charging devices using sun and vibration harvesting. A battery receives the remaining energy for recharging while the charging current level can be checked. The entire system built using the MATLAB/SIMULINK environment, performances are monitored by the simulation results and validated experimentally.

“…Further there are many studies those are done on the three phase systems and the different control strategies are implemented like primary inductances in PV side [11], neuro fuzzy controllers and honey bee algorithm [12], and multiple inputs like wind and DG sets are employed [13] to obtain better outputs and reduced harmonics. Multi level inverters like 5-level inverters [14] are also discussed for reducing harmonics. But these techniques can only be implemented majorly for 3-phase systems not for single phase.…”

This project proposes a topology for Fuzzy PI controller based single-phase Hybrid solar photovoltaic (PV) inverter with for Domestic applications. The proposed Hybrid power converter consists of a PV cells, MPPT algorithm, switched mode buck boost converter in the DC side, battery bank and a single phase bridge inverter. The Control strategy of the inverter gate pulses are done by the sampling of sinusoidal pulse width modulation (SPWM) with a square wave which is controlled by Fuzzy and PI combined controller, along with grid synchronization condition. The performance of the proposed inverter is simulated under grid-connected scenario and load disturbances. The output of PV module system is enhanced by the maximum power point tracking (MPPT) technique using P & O algorithm in order to increase the systems efficiency. This system is more useful for the households as it has both power storing and saving applications.
