Abstract :
An average model of SEPIC power converters operating in continuous current mode (CCM) was developed and verified against cycle-by-cycle simulation. The proposed model is compatible with SPICE and other modern electronic circuit simulators and can be used to run DC (static transfer function), AC (small signal, frequency domain) and TRAN (large signal, time domain) analyses. The model is developed in terms of the average, large signal behavior while the small signal (AC) response is worked out automatically by the simulator. An extension to current programmed SEPIC for the case of peak current mode (PCM) control is also presented. This paper treats the case of SEPIC with uncoupled inductors
