PSIM Simulation of Flyback Converter for P&O and IC MPPT Algorithms

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.
