An efficient single-switch voltage regulator

In this paper a single-switch voltage regulator is presented. The converter processes the power less than once, resulting in an efficient design. Although the current is not sinusoidal, the proposed converter complies with the Standard IEC 1000-3-2 about low frequency harmonics for a medium power stage. Additionally a fast regulation at the output voltage is obtained due to the fact that sliding mode control is used. Analysis, simulation and experimental results of the converter are presented.
