Abstract
In this research, an enhanced positive output super-lift Luo (EPOSLL) converter is utilized to track maximum power of photovoltaic (PV) source. Further, the drift avoidance perturb and observe (P&O) maximum power point tracking (MPPT) technique is adopted to track maximum power. Also, the two control strategies are proposed with the help of proportional integral (PI) controller to maintain constant output voltage and output power, respectively. The MATLAB/Simulink software is utilized to simulate the entire research work. Results demonstrate that the proposed converter design not only tracks the maximum power but also it maintains the output voltage and power to a fixed set value. Also, the solar irradiance (G) is varied and it is observed that the output voltage and output power are constant at all time and gain high significance in motor drive applications.
