“…Perturb and Observe algorithm is the most popular method of tracing the MPP. This control algorithm has some disadvantages as described in [13], which P&O algorithm does not have ability to compare the terminal voltage value of the array with actual operating value of voltage at maximum power point [14]. In this study, selection of MPPT Incremental Conductance control algorithm is the finest resolution because it is easier to appliance, more efficient, higher speed of tracking.…”

The representation of this paper is a different approach to get efficient high brightness of LED lighting operating with high gain buck boost converter controlled by efficient incremental conductance MPPT controller algorithm of solar PV module. The mathematical modeling associated with process of simulation for solar panel, high gain buck boost topology and efficient MPPT controller is discussed clearly in this paper. Conventional converters are applied and analyzed for the LED lighting system in literature, but these are not preferred due to lack of efficient performance, high harmonic distortion and low power factor. The projected buck-boost structure is modified structure of high gain buck-boost structure. The comparison between projected converter and existing power converter is clearly summarized in this paper. The switching as well as conduction losses are very low due to single switch operating without transformer. The cost of the solar based LED lighting system with high conversion ratio buck-coost converter is very cheap because the number of semiconductor devices and passive components are using low. In this paper 120W and 30W of LED lighting system is planned and executed in MATLAB/SIMULINK. The clear summary of outcomes will prove the system is efficient

“…Two input boost along with a switchedinductor impedance-network proposed in [17], which yields DC voltage magnitude of a desired level with lower ripple and has high conversion efficiency. In [18], a 120 W LED lighting system energized from a photovoltaic panel through a high gain converter is proposed and the analysis is done at a constant irradiation level. A new hybrid high gain converter with a lesser number of components is proposed in [19] with less stress in devices and more efficiency.…”

The demand for electricity is rapidly growing and renewable energy sources such as solar, wind and tidal energy can compensate the demand to a substantial level. Among these, solar energy is abundant, scalable and is cheaper. The generated energy can be used in an efficient way if the DC output is directly supplied to the load instead of converting it to AC. Every electrical system is capable of operating in DC and, for example, energy efficient Light Emitting Diode (LED) lights have become popular as they provides more lumens with less power consumption and also can be directly operated from DC. LED lighting system in large commercial buildings has irradiance levels which vary sigificantly during operation. Extracting maximum power from the energy system and maintaining constant voltage output at different loads is another challenge. This paper proposes a solar Photo Voltaic (PV)-based energy system including Battery Energy Storage System (BESS) for supplying LED lamps to a commercial building through a modified high gain Luo converter. The Perturb and Observe control algorithm has been used for maximum power extraction from a PV cell whereas PI (Proportional Integral) controllers maintain constant output voltage from PV–BESS against different irradiance levels. To supply the desired voltages to the LED lighting system, a modified high gain Luo converter is designed. To make the output voltage constant at different load currents, PI and Sliding Mode Controllers (SMC) are designed with the help of the state-space average model. It is found that the sliding mode controller outperforms the PI controller in terms of behavior in the transient period and tracking capability. The system is simulated using MATLAB/Simulink®. The Sliding Mode Controller has a 95% less transient period and is 75% faster in tracking capability when compared to other controllers. The system could be incorporated with the PV source to obtain green energy.
