Modeling and performance evaluation of a DC/DC SEPIC converter

Abstract

The use of the CC-PWM switch model for the average large and small-signal modeling of a current-programmed control DC-to-DC SEPIC converter, operating in the continuous conduction mode is presented. Derivation of the model and its use in the performance evaluation of a practical 5 V regulator are shown. Predicted simulation results are confirmed by measurements for both load transient and the loop-gain frequency response for stability conditions.<>
