| Abstract: | This paper presents the details involved in constructing the models of PWM DC/DC converters operating in continuous conduction mode（CCM） using the dynamic phasors.A systematic method is presented including large-signal circuit models,ripple calculation,model simplification using SMA,and small-signal circuit models.As an example,a procedure of modeling the PWM BUCK/BOOST Bi-directional DC/DC Converter is detailed,the simulation results are presented to show the effective of this method. |
| Keywords: | dynamic phasor converters small-signal circuit models |
