Abstract

Flyback converters are widely used for photovoltaic (PV) application. However, the majority of research has been focusing on the control aspect of the converter where as stability, especially sensitivity of design parameters, has not been well studied. This paper presents the small-signal modeling of flyback converters in continuous conduction mode (CCM) using a moving average technique. MATLAB/Simulink is used to find the eigenvalues of the closed-loop system. The system stability is analyzed through the movement of eigenvalues due to changes in parameters of different components. The developed model demonstrates stability issues when certain parameters such as controller gains and passive components' values.
