Abstract :
The paper describes a method for finding steady states in switched DC-DC converters, which is based on the SPICE bias point computation rather than a time-consuming transient analysis. The switched converter is modeled by unified substitutive circuits whose DC analysis determines directly the limit values of steady-state circuit variables at time instants when switches change their states. From these values one can derive e.g. the output voltage ripple or restore completely the steady-state signals.
