Analysis and design of power gyrators in sliding-mode operation

The use of sliding-mode techniques and the insertion of damping networks in fourth-order convertors with both input and output filters lead in certain cases to a stable equilibrium point with gyrator characteristics. The buck convertor with input filter and the Cˇuk convertor are shown to have stable dynamics and an equilibrium point with gyrator characteristics for certain parameter values. The analytical predictions are verified by means of simulation and experimental results.
