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 %.
