Abstract
The small-signal transfer function model for a Cuk step-down converter, in continuous conduction mode, is presented. This leads to a non-minimum phase transfer function representing the output voltage response to perturbations of the switch duty ratio. The analysis of this circuit operating in discontinuous modes is described in detail and the non-linear relationships between input and output voltages are derived.
