Abstract :
This work is devoted to the design of a sliding feedback control scheme for a boost-buck converter for AC signal tracking task. Two sliding surfaces are proposed to control the boost and the buck stages respectively. As a result, an output sinusoidal amplitude greater than the dc converter input voltage can be obtained in a large frequency range. Simulation and experimental results with for both linear and nonlinear loads validating the design are also presented
