The performance of a Multiple-Lift Push-Pull Switched-Capacitor Luo-Converter for
Photovoltaic (PV) applications is investigated in this paper. Further, the two different
control algorithms namely PI and Fuzzy algorithms are adopted to maintain constant
output voltage. To track maximum power, the drift avoidance Perturb & Observe
(P&O) Maximum Power Point Tracking (MPPT) technique has been used. The
simulation output justifies that the better steady state and high settling time in the
output voltage is achieved with Multiple-Lift Push-Pull Switched-Capacitor Luo
(PPSCL) Converter with fuzzy control when compared to Multiple-Lift PPSCL with PI
controlled converter.
