Abstract :
Computer-aided design of a switching power converter is benefited by the use of a model which runs on SPICE, and which simulates the DC, small-signal AC, and transient response of both the continuous-conduction mode and the discontinuous-conduction mode. This study presents such modes for the three basic types of converters (buck, boost, and buck-boost) in both the duty-cycle-programmed and the current-programmed variety. A set of formulas is presented which describe the small-signal response of current-programmed power converters in the discontinuous-conduction mode
