Summary:
In this paper, the nonlinear dynamical behavior and stability analysis of a high-voltage-gain quadratic boost converter fed by a photovoltaic (PV) source is addressed. Using the nonlinear models of the converter, the PV source and the MPPT controller, the dynamics of the system are explored in terms of the irradiance using the circuit-level switched model implemented in PSIM software. The time domain simulations show that at relatively high irradiance levels, the system may exhibit undesired subharmonic oscillations and the Maximum Power Point Tracking control cannot make the system to work in the maximum power as desired.
