In this work, the describing function technique is applied to a two-rules fuzzy controller for switching regulators, in order to establish the scaling factors boundaries for which the system presents an oscillatory behavior, thus facilitating the fuzzy controller design. Simulation results for a boost converter are presented to illustrate the method.
