An average model of SEPIC converters with coupled inductors was developed and verified against cycle-by-cycle simulations. The model can be used as is by any modern circuit simulator to run steady state (DC), large signal (transient) and small signal (AC) analyses. The inductors coupling coefficient, incorporated as a parameter in the model, can be varied from zero to almost unity. Zero coupling coefficient represents the case of a SEPIC converter with uncoupled inductors.
