Abstract :
This paper gives an idea about Sliding Mode Controller (SMC) implementation to a DC-DC Boost Converter for a Photovoltaic (PV) system to track Maximum Power Point (MPP). SMC implementation meets three steps (i) Hitting condition, (ii) Existance condition and (iii) Stability condition. Single diode PV model is designed for lighting applications, and PV output is connected to a Boost converter to regulate and increase the voltage upto desired level. SMC is implemented in a feedback manner with capacitor voltage and inductor current. The steady state condition occured very quickly i.e., before 0.1sec, and the results of SMC are compared with PI controller. The models are simulated in MATLAB/SIMULINK.
