Abstract

Flyback converters are used in automotive power supply applications for their advantage of galvanic isolation and the low number of components on a small PCB area. This paper is dedicated to state space analysis of flyback converter with parasitic elements. The Euler method also uses state-space matrices of the proposed flyback converter with nonideal flyback converter with a Bode plot of both open-loop and closed-loop systems. The advantage of this approach is to determine the stability of the open-loop system from a mathematical model and to estimate suitable PI tuning values for the closed-loop system. Transfer function and Bode plots have been obtained from state space matrices in MATLAB.
