摘要:
A bond graph approach is proposed for the modeling and simulation of switched DC-to-DC power converters of the boost type, regulated by means of a pulse-width-modulation (PWM) strategy. An average bond graph model of the PWM regulated DC-to-DC power converter is derived using ideal lossless transformer elements. The proposed bond graph model constitutes an “input” to a computer aided package, called DESIS, which automatically generates the system model as a set of differential equations with explicit control parameters. The computer package is also capable of simulating both the average and the actual discontinuous PWM regulated responses of the DC-to-DC power converter for a given feedback duty ratio policy.
