✦ Synopsis

The occurrence of nonlinear phenomena in DC-DC power converters makes their analysis and control difficult. We propose a converter model that takes into account the internal resistances of the converter elements. A fuzzy logic controller is then used to shift the nonlinear phenomena outside the operating domain, and to ensure current regulation over a wide range of parameters. To validate the achieved performance, a comparative study is presented.

## Abstract This letter presents a single‐stage soft‐switched full‐bridge AC/DC converter for low‐voltage/high‐current output applications. A phase‐shifted method with a variable frequency control is used to regulate the DC bus voltage and the output voltage of the single‐stage AC/DC converter. The

An algorithm, based on fuzzy logic, for controlling chaos in a nonlinear fiber ring resonator is presented. The main ad¨antage of using fuzzy logic is the a¨oidance of knowing the nonlinear differential equation that models the resonator. The algorithm is described, simulations are performed, and th
