Abstract

Design and enhancement of an efficient lighting system is the pressing priority for ensuring Sustainable Development Goa1-7 Affordable and clean energy. Solar energy has been preferred as a source since it is clean energy source with net-zero carbon and has incredible potential energy which can be captured using a diverse range of easily accessible equipment for residential and commercial applications, with the added benefit of low hassle and zero operational cost. Despite the fact that solar energy is abundant throughout the world, the tracking of power towards its optimal operation PV systems is a critical component of achieving higher conversion. The MPPT method based on incremental conductance (IC) is used here. In this work, energy to light up an Light Emitting Diode (LED) is obtained from a 40 Watts, 12 Volts Solar Panel. This voltage is amplified by implementing a DC/DC Boost converter. After obtaining a reference voltage from the MPPT, the set point for the current is reaped from a brightness control circuit which receives input from a light detecting sensor. The DC/DC Boost Converter considered here is modelled using small signal modelling technique by accounting for non-idealities produced by inductors' and capacitors' electro-resistance (ESR) and voltage variations created by the presence of a diode. The challenges brought on by the DC/DC Boost converter's right half plane zero are construeed, and a proportional plus integral controller is suggested to alleviate the associated control constraints. Using MATLAB simulation studies, the photometric parameters were computed from the observed values to appraise the dominance of the LED driver. Power calculations are performed to prove the proposed converter's effectiveness. Comparison among IMC approach and Roberto method is done and it is inferred that Roberto method is proven to be effective. © 2022 IEEE.
