Abstract

An average model of SEPIC converters with coupled or uncoupled 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 leakage inductances were taken into account and treated separately from the mutual inductance. The primary and secondary coupling coefficients were incorporated as parameters. The coupling coefficients can be from zero to almost one, representing the complete range of possible SEPIC topologies
