Abstract

The output power of PV panels varies
continuously depending on some environmental factors such as temperature,
shading and solar radiation level and load conditions. PV panels have a
nonlinear characteristic since they have different output power at different
operating points. Therefore, dc-dc converters are required between PV panels
and load to obtain the maximum power from the panels. In this study, the
simulation of the flyback converter for two most commonly used MPPT algorithms
specifically Perturb and Observe (P&O) method and Incremental Conductance
(IC) method are achieved in PSIM and performance of the control techniques are
compared. The simulation results of P&O and IC MPPT algorithms are compared
for different solar radiation conditions.
