Abstract :
A computational method for modeling a switch mode converter, including power stage and pulse-width modulator is presented. The agreement between the dynamic characteristics obtained by the proposed approach and the state-space averaging approach is shown. The only analytical work involved is the derivation of the equivalent circuits for a given converter in state-space representation. The developed computer simulation program then provides a good approximated small-signal model of the switch mode converter at a given operating point for use in the feedback loop design process
