Abstract :
The paper deals with symbolic analysis of switched DC-DC converters operating in the continuous conducting node (CCM). The method is based on the technique of generalized average model of PWM switch. A procedure for obtaining line-to-output and control-to-output transfer functions for all basic topologies in fully symbolic form using the SNAP programme is shown. An example of the analysis of a boost converter is presented.
