Abstract :
This paper presents the bond graph modeling and simulation of a switched dc-to-dc power converter of the boost type, regulated by means of a pulse-width-modulation (PWM) strategy. Two models are presented, the average model, which represents the switch as an ideal linear transformer element and the actual (discontinuous) model, which represents it as a non-linear transformer element whose function is a non-periodic pulse train taking values in the discrete set {0,1}. Both transforms are modulated by the pulse width. The bond graphs were simulated and both the average and the actual discontinuous PWM regulated responses of the dc-to-dc power converter for a given feedback duty ratio policy were obtained
