Sažetak
In this study, an improved chopper is implemented for current extraction, enhanced solar power generation control, and increased voltage. A simplified space vector control technique is applied to operate the permanent-magnet brushless DC drive (PMBLDC) by controlling the inverter operation. This is used as a special electrical machine with reliable operation and maintenance control. This system uses the Perturb and observer (P&O) algorithm which maximises the PV-system output power and reduces the overall cost. A fuzzy logic controller (FLC) is used to control the duty cycle and increase the PV voltage. The modified multilevel inverter (MMLI) reduces harmonic distortions and low-switching losses by using a self-tuning filter (STF). This study achieved a better PMBLDC system performance, an improved efficiency, and eliminated the total harmonic distortion (THD) by the self-tuning filter with and without using MATLAB/SIMULINK.
