Performance Evaluation of SRBC Circuit using MPPT Controller

The Maximum Power Point Tracker integrated with Synchronous Rectifier Buck Converter circuit is used to increase the output voltage and current. In this work, Maximum Power Point Tracker (MPPT)’s characteristics, performance, operation modes, advantages, and disadvantages are analyzed and observed. PSpice and MATLAB are chosen in designing and simulating the circuits. The analysis is carried out based on the average output voltage and current, node voltage, output ripple voltage and current, gate-to-source voltage, and body diode conduction loss of the MPPT circuit. It is found that by implementing MPPT controller with SRBC, the output voltage and output current have increased by approximately 12 % - 13 % for both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) conditions. It also reduces output voltage ripple and current around 70 % in CCM mode. However, in DCM, the output peak-to-peak ripples for both voltage and current have increased by 20 %.
