| Abstract |
In this paper the analysis and design of the sliding mode control of a coupled-inductor Cuk converter under conditions of order reduction are presented. Starting from the converter state equations in normalized form, the expression for the equivalent control is derived and the conditions established for sliding motions. Therefore, two sliding surfaces are analyzed. Namely, the surface representing the constant magnetizing current and the surface corresponding to the constant transference voltage. In both cases, conditions for stability of the equilibrium points are introduced. Subsequently, the sliding mode control circuit corresponding to the constant magnetizing current is implemented. Experimental results are in agreement with the theoretical predictions. |
